실험 절차

A 25-mL round bottom flask was charged with methyl 2-(4-((2-(cyclopentyloxy)-6-(trifluoromethyl)pyrimidin-4-yl)methyl)phenyl)acetate (0.069 g, 0.17 mmol) and dichloromethane (6 mL) at 0° C. A 1M solution of DIBAL-H in THF (0.70 mL, 0.70 mmol) was added and the resulting solution was stirred at 0° C. for 1 h until the starting material was consumed (monitored by LCMS analysis). The reaction was quenched with methanol then absorbed onto silica (2 g) and concentrated under reduced pressure. Purification by column chromatography on silica using hexanes/ethyl acetate (10:0 to 1:1) as the eluent afforded the title compound (0.055 g, 87%) as a white solid. MW=366.38. M.p. 48-50° C. 1H NMR (DMSO-d6, 500 MHz) δ 7.51 (s, 1H), 7.23 (d, J=7.5 Hz, 2H), 7.16 (d, J=8.0 Hz, 2H), 5.38-5.32 (m, 1H), 4.58 (t, J=5.5 Hz, 1H), 4.09 (s, 2H), 3.56 (q, J=6.0 Hz, 2H), 2.68 (t, J=7.0 Hz, 2H), 2.00-1.89 (m, 2H), 1.77-1.66 (m, 4H), 1.66-1.55 (m, 2H); APCI MS m/z 367 [M+H]+.
