실험 절차
To a solution of 4-(3-chloro-4-methoxybenzylamino)-5-methoxycarbonyl-2,6-dichloropyrimidine (prepared in the above (2)) 1.01 g in dimethylformamide 10 ml are added 4-hydroxypiperidine 338 mg and triethylamine 411 mg at room temperature, and the mixture is stirred for 15 minutes. The reaction mixture is diluted with water and extracted with ethyl acetate. The organic layer is washed, dried and concentrated in vacuo to give a slightly yellow oil. The oil is separated with silica gel chromatography (solvent; chloroform:ethyl acetate=8:1→5:1), and further separated with silica gel chromatography (solvent; hexane:ethyl acetate=1:1) to give 4-(3-chloro-4-methoxybenzylamino)-5-methoxycarbonyl-6-chloro-2-(4-hydroxypiperidin-1-yl)pyrimidine as colorless crystals 540 mg (mp 138-139° C.) and 4-(3-chloro-4-methoxybenzylamino)-5-methoxycarbonyl-6-(4-hydroxypiperidin-1-yl)-2-chloropyrimidine as a colorless foam, 617 mg.
