实验过程

To a suspension of 3,4-dihydro-6-(3,4-dimethoxyphenyl)-3-methyl-2-(1-piperazinyl)-4-(2,4,6-trimethylphenylimino)pyrimidine (0.31 g) in tetrahydrofuran (10 ml) were added triethylamine (0.11 ml) and 4-fluorobenzoyl chloride (0.69 ml). The mixture was stirred at ambient temperature for an hour and the reaction was quenched by adding methanol (5 ml). After evaporation of the solvent, the residue was dissolved in ethyl acetate. The solution was washed with water, dried over magnesium sulfate and evaporated in vacuo. The residue was chromatographed on silica gel using a mixture of chloroform and methanol (95:5) to give 3,4-dihydro-6-(3,4-dimethoxyphenyl)-2-[4-(4-fluorobenzoyl)piperazin-1-yl]-3-methyl-4-(2,4,6-trimethylphenylimino)pyrimidine (0.34 g).
