实验步骤: 2-(2-Methylphenyl)acetyl chloride (9.9 g, 58.8 mM) was added to a stirred suspension of calcium carbonate (7.87 g, 78.7 mM) and 4-amino-2,6-dimethylphenyl thiocyanate (7 g, 39.3 mM) in dry THF (150 mL). The mixture was stirred for 1 hour. Water (1000 mL) was added. The mixture was acidified to pH4 with 2M HCl and extracted with ethyl acetate. The combined extracts were washed with water, then with saturated sodium chloride solution and dried (MgSO4). The solvent was removed by evaporation. The pale green solid obtained was triturated with ether to give 2,6-dimethyl-4-[2-(2-methylphenyl)acetamido]phenyl thiocyanate (B), as a cream coloured solid in 83% yield; NMR (CDCl3, 200 MHz): 2.47(s, 3H), 2.49(s, 6H), 3.69(s, 2H), 7.14-7.17(m, 4H), 7.55(s, 2H), 10.27(s, 1H). extracted with ethyl acetate The combined extracts were washed with water with saturated sodium chloride solution and dried (MgSO4) The solvent was removed by evaporation The pale green solid obtained was triturated with ether

实验步骤: To a stirred and cooled (0° C.) solution of 7 parts of 4-[1-(1H-imidazol-1-yl)propyl]-2-nitrobenzenamine in 126 parts of 1,2-dichloroethane were added 9.6 parts of 2-methylbenzeneacetyl chloride. After stirring for 12 hours at room temperature, the reaction mixture was poured into ice water and the product was extracted with dichloromethane. The extract was dried, filtered and evaporated in vacuo. The oily residue was purified by column chromatography over silica gel using a mixture of dichloromethane and methanol (98:2 by volume) as eluent. The eluent of the desired fraction was evaporated, yielding 9.6 parts (89.3%) of N-[4-[1-(1H-imidazol-1-yl)propyl]-2-nitrophenyl]-2-methylbenzeneacetamide; mp. 122° C. (interm. 48). After stirring for 12 hours at room temperature the product was extracted with dichloromethane The extract was dried filtered evaporated in vacuo The oily residue was purified by column chromatography over silica gel using a mixture of dichloromethane and methanol (98:2 by volume) as eluent The eluent of the desired fraction was evaporated

实验步骤: A mixture of 2.0 mmol of 10,11-dihydro-10-(6-amino-3-pyridinylcarbonyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepine, 2.1 mmol of 2-methylbenzeneacetyl chloride and 5 mmol of triethylamine in 10 ml of dichloromethane is stirred under argon at room temperature for 16 hours. The solvent is removed under vacuum and the residue partitioned between 50 ml of ethyl acetate and 25 ml of water. The organic layer is separated, washed with H2O, 1N NaHCO3, brine and dried (Na2SO4). The solvent is removed and the residue chromatographed on silica gel with ethyl acetate-hexane as solvent to give the product as a solid. The solvent is removed under vacuum the residue partitioned between 50 ml of ethyl acetate and 25 ml of water The organic layer is separated washed with H2O, 1N NaHCO3, brine dried (Na2SO4) The solvent is removed the residue chromatographed on silica gel with ethyl acetate-hexane as solvent

实验步骤: To a chilled solution (0° C.) of 5.0 g of methyl 6-aminopyridine-3-carboxylate and 12.6 ml of diisopropylethylamine in 40 ml of dichloromethane under argon is added 12.2 g of 2-methylbenzeneacetyl chloride in 10 ml of dichloromethane. The mixture is stirred at room temperature 16 hours and diluted with 200 ml of dichloromethane and 50 ml of water. The organic layer is separated and washed with 50 ml each of 1M NaHCO3, brine and dried (Na2SO4). The solution is filtered through a thin pad of hydrous magnesium silicate and the filtrate concentrated to dryness. The residue (9.0 g) is purified by chromatography on silica gel with hexaneethyl acetate (3:1) as eluent to give 0.70 g of methyl 6-[[bis(2-methylbenzeneacetyl)]amino]pyridine-3-carboxylate and 8.6 g of a mixture of methyl 6-[(2-methylbenzeneacetyl)amino]pyridine-3-carboxylate and the bis acylated product. The above mixture (8.6 g) of mono and bis acylated product is dissolved in 60 ml of tetrahydrofuran-methanol (1:1) and 23 ml of 5N NaOH is added. The solution is stirred at room temperature for 16 hours, concentrated under vacuum, diluted with 25 ml of H2O and acidified with cold 1N HCl. The precipitated solid is filtered off and dried to give 5.9 g of white solid. The organic layer is separated washed with 50 ml each of 1M NaHCO3, brine dried (Na2SO4) The solution is filtered through a thin pad of hydrous magnesium silicate the filtrate concentrated to dryness The residue (9.0 g) is purified by chromatography on silica gel with hexaneethyl acetate (3:1) as eluent
