Reaction Steps

To a solution of 2-(4-((2-(3-chlorophenyl)-5,5-dioxido-7,8-dihydro-6H-thiopyrano[3,2-d]pyrimidin-4-yl)methyl)phenyl)acetic acid (0.040 g, 0.090 mmol) in DMF (2 mL) was added EDC (0.034 g, 0.18 mmol), HOBT (0.024 g, 0.18 mmol) and ammonia in methanol (0.13 mL, 0.90 mmol). The mixture was sealed and stirred at 85° C. for 16 h. The mixture was diluted with ethyl acetate and then washed with water. The organic layer were dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by column chromatography (silica, dichloromethane/ethyl acetate) to afford the title compound (0.025 g, 62%) as a white solid. MW=441.93. 1H NMR (DMSO-d6, 500 MHz) δ 8.30-8.26 (m, 2H), 7.69-7.64 (m, 1H), 7.61-7.56 (m, 1H), 7.40 (s, 1H), 7.37 (d, J=8.0 Hz, 2H), 7.19 (d, J=8.0 Hz, 2H), 6.82 (s, 1H), 4.52 (s, 2H), 3.77-3.71 (m, 2H), 3.32 (s, 2H), 3.21 (t, J=6.5 Hz, 2H), 2.40-2.38 (m, 2H); APCI MS m/z 442 [M+H]+.
