実験手順
A mixture of 3 g of 2-chloro-6-methyl-4-phenyl-thieno[2,3-d]pyrimidine, 2.2 g of 1-benzyl-3-methylpiperazine, 1.1 g of sodum carbonate and 4 ml of dimethylformamide is reacted under reflux for 3 hours. After cooling, 80 ml of benzene and 80 ml of water are added and two layers are separated. The benzene layer is washed twice with 100 ml of water and then with saturated aqueous sodium chloride solution, and dried over anhydrous sodium sulfate. After distilling off benzene, purification of the product by silica gel chromatography using 180 g of silica gel and n-hexane/ethyl acetate (10:1) as an eluent is carried out. There is obtained 4.3 g of oily 2-(4-benzyl-2-methylpiperazinyl)-6-methyl-4-phenyl-thieno[2,3-d]pyrimidine.
