Reaction Steps

A 8-mL vial was charged with 2-(4-aminophenyl)acetonitrile (40 mg, 0.3 mmol, 1.25 eq.), [2-(3-chlorophenyl)-7,8-dihydro-6H-thiopyrano[3,2-d]pyrimidin-4-yl]trifluoromethanesulfonate (100 mg, 0.24 mmol, 1. eq.) and DMF (1 ml). The resulting mixture was stirred at 70° C. overnight. After cooling to room temperature, water was added to the mixture (5 ml). The precipitate was collected by filtration and washed with water (20 ml). After drying, the crude product was purified by chromatography on silica gel using hexane/dichloromethane (1:1, 1:1.5 then 1:2) as eluent to give the title compound (35 mg, 37% yield).
