实验步骤: 3-(4-Hydroxy-3-methylphenyl)-1-(5-(4-(trifluoromethyl)phenyl)thien-2-yl)prop-2-en-1-one is prepared from 1-(5-(4-(trifluoromethyl)phenyl)thien-2-yl)ethanone and 4-hydroxy-3-methylbenzaldehyde according to general procedure B. The evaporation residue is washed with dichloromethane. The evaporation residue is washed with dichloromethane

反应条件: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of DIAD (395 μL, 2.15 mmol) in THF (0.8 mL) was added dropwise to a solution of 11-ethyl-5,11-dihydro-8-(2-hydroxyethyl)-5-methyl-6H-dipyrido[3,2-b:2′,3′-e][1,4]diazepin-6-one (430 mg, 1.44 mmol), 4-hydroxy-3-methylbenzaldehyde (200 mg, 1.47 mmol) and PPh3 (564 mg, 2.15 mmol) in THF (15 mL) at 25° C. The mixture was stirred at 25° C. for 16 h. The reaction mixture was concentrated under reduced pressure and the residue was purified by flash chromatography (EtOAc:toluene, 1:3) to yield the title compound (385 mg, 64% yield). The reaction mixture was concentrated under reduced pressure the residue was purified by flash chromatography (EtOAc:toluene, 1:3)

实验步骤: To a solution of 4-hydroxy-3-methylbenzaldehyde (900 mg, 6.61 mmol) in CH2Cl2 (19 mL) was added Et3N (5.90 mL, 42.3 mmol) and chloromethyl methyl ether (2.00 mL, 26.3 mmol). The reaction was stirred at 25° C. for 16 h. The reaction mixture was diluted with EtOAc and was successively washed with aqueous 1 N HCl solution, aqueous saturated NaHCO3 solution, water and brine, dried (MgSO4), filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (Hexane:EtOAc, 4:1) to give the title compound (630 mg, 53% yield) as a clear oil. was successively washed with aqueous 1 N HCl solution, aqueous saturated NaHCO3 solution, water and brine dried (MgSO4) filtered concentrated under reduced pressure The residue was purified by flash chromatography (Hexane:EtOAc, 4:1)
