实验步骤: To a stirred solution of 4-(iso-butyryl-N-methylamino)-benzoic acid (0.088 g) and triethylamine (0.041 g) in chloroform (4 ml) was added a solution of ethyl chlorformate (0.049 g) in chloroform (1 ml). The mixture was stirred under an N2 atmosphere at room temperature for 1½ hours and then cooled to 0° C. N,N-Diethyl-propylenediamine (0.051 g) in chloroform (1 ml) was added and the mixture was stirred over night. The mixture were washed with 0.5 M NaOH(aq) and water. Drying and evaporation of the solvent gave a residue, which was chromatographed on a silica gel column first eluted/washed with ethylacetate and then eluted with ethylacetate-methanol-triethylamine (12:4:1) to yield 0.098 g, of the title product. cooled to 0° C the mixture was stirred over night The mixture were washed with 0.5 M NaOH(aq) and water Drying evaporation of the solvent gave a residue, which was chromatographed on a silica gel column first eluted/washed with ethylacetate eluted with ethylacetate-methanol-triethylamine (12:4:1) to yield 0.098 g

实验步骤: A mixture of 12.15 g (0.075 mole) of 1,1'-carbonyl diimidazole and 7.50 g (0.0476 mole) of 1-diethylamino-2-propanamine in 400 ml of tetrahydrofuran was stirred at room temperature for 1 hr. A solution of 12.26 g (0.054 mole) of N-[2-(phenylsulfonyl)ethyl]-2-propanamine in 50 ml of tetrahydrofuran was added, and the solution was refluxed for 19 hr. The solvent was removed in vacuo, and the residue was dissolved in a 50/50 mixture of methylene chloride and ether. The organic solution was extracted with several portions of water and was dried over magnesium sulfate. The solvent was removed in vacuo to give an oil. Flash chromatography on silica gel (elution with methanol) gave 10.87 g (52.3 g) of clear colorless oil. 1H NMR (CDCl3)δ7.5-8.15 (m, s. aromatic), 5.35 (br s, 1, NH), 4.1 (m, 1, (CH3)2CH), 3.45-4.0 (m, 1.
