Reaction Steps

A 8-mL vial was charged with 2-[4-[[2-(3-chlorophenyl)-7,8-dihydro-6H-thiopyrano[3,2-d]pyrimidin-4-yl]amino]phenyl]acetonitrile (32 mg, 0.081 mmol, 1 eq.), azido(trimethyl)silane (0.2 ml, excess) and tetrabutylammonium fluoride hydrate (50 mg, 0.19 mmol, 2.3 eq.). The mixture was stirred at 110° C. overnight. After cooling to room temperature, the mixture was partitioned between dichloromethane (4 ml) and 2N HCl (4 ml). The solid was collected by filtration and washed with water (10 ml) followed dichloromethane (10 ml). After drying, the title compound was obtained as HCl salt (25 mg, 65% yield).). MW/HCl=472.39. 1H NMR (400 MHz, DMSO-D6) δ 8.6 (brs, 1H), 8.16 (s, 1H), 8.11 (d, J=7.2 Hz, 1H), 7.64 (d, J=8.4 Hz, 2H), 7.53 (m, 2H), 7.29 (d, J=8.4 Hz, 2H), 4.31 (s, 2H), 3.21 (d, J=5.6 Hz, 2H), 2.94 (d, J=6.4 Hz, 2H), 2.19 (m, 2H).
