Reaction Steps

The thus synthesized compound 2-chloro-3-(4-chlorophenyl)-7-phenyl-2,3-dihydrothieno[3,2-d]pyrimidin-4(1H)-one (22.7 mg, 0.06 mmol) was mixed with a solution of N,N-dimethylamine (3 ml) and diisopropylethylamine (0.01 ml, 0.06 mmol) in THF. The mixture was heated with stirring at 65° C. overnight. After the completion of the reaction was confirmed by TLC, the reaction mixture was cooled to room temperature and separated with water and dichloromethane. The extracted organic layer was washed with brine, dried over anhydrous MgSO4, and filtered. The filtrate was distilled under reduced pressure. The concentrate was purified by silica gel column chromatography (EtOAc:Hex=1:5) to give 14.1 mg (0.037 mmol, 62% yield) of the title compound.
