Reaction Steps

A 20-mL vial was charged with methyl 2-(4-((2-(cyclopentyloxy)-6-(trifluoromethyl)pyrimidin-4-yl)methyl)phenyl)acetate (0.150 g, 0.38 mmol) in methanol (2 mL). To this mixture was added NH3 (10.8 mL, 7N in methanol, 76.0 mmol). The vial was sealed and the resulting mixture was stirred at 100° C. for 23 h. The crude reaction solution concentrated under reduced pressure. The residue was purified by chromatography on silica using hexanes/ethyl acetate (10:0 to 0:10) as eluent followed by chromatography on silica using dichloromethane/methanol (10:0 to 96:4) as eluent to afford the title compound (0.066 g, 46%) as a white solid. MW=379.38. M.p. 130-132° C. 1H NMR (DMSO-d6, 500 MHz) δ 7.51 (s, 1H), 7.41 (br s, 1H), 7.26 (d, J=8.0 Hz, 2H), 7.20 (d, J=8.0 Hz, 2H), 6.83 (br s, 1H), 5.35 (septet, J=3.0 Hz, 1H), 4.10 (s, 2H), 3.33 (s, 2H), 2.00-1.90 (m, 2H), 1.77-1.66 (m, 4H), 1.65-1.55 (m, 2H); ESI MS m/z 380 [M+H]+.
