Reaction Steps

A 8-mL vial was charged with [2-(3-chlorophenyl)-7,8-dihydro-6H-thiopyrano[3,2-d]pyrimidin-4-yl]trifluoromethanesulfonate (100 mg, 0.243 mmol, 1 eq.), 2-(4-aminophenyl)acetic acid (37 mg, 0.245 mmol, 1 eq.) and DMSO (1 ml). The resulting mixture was stirred at 110° C. under Ar for 6 hr. After cooling to room temperature, water was added to the mixture (15 ml). The precipitate was collected by filtration and washed with water (15 ml). After drying, the title compound was obtained (97.5 mg, 97% yield). The product thus obtained was forwarded to the next step without any further purification.
