A 25-mL round bottom flask was charged with methyl 2-(4-((2-(3-chlorophenyl)-6-cyclopropylpyrimidin-4-yl)methyl)phenyl)acetate (0.149 g, 0.38 mmol) and THF (5 mL) at Borane-dimethylsulfide complex (0.108 mL, 1.13 mmol) was added and the resulting solution was stirred at 55° C. for 2.5 h until the starting material was consumed (monitored by LCMS analysis). The reaction was quenched with methanol then treated with 2N aqueous HCl (5 drops) and concentrated under reduced pressure. The residue was diluted with methanol and then concentrated under reduced pressure. The residue was absorbed onto silica (2 g) and purified by column chromatography on silica using hexanes/ethyl acetate (10:0 to 3:1) as the eluent to afford the title compound (0.113 g, 82%) as a colorless oil. MW=364.87. 1H NMR (DMSO-d6, 500 MHz) δ 8.31-8.27 (m, 2H), 7.59-7.51 (m, 2H), 7.27 (s, 1H), 7.26 (d, J=8.0 Hz, 2H), 7.16 (d, J=8.0 Hz, 2H), 4.58 (t, J=5.0 Hz, 1H), 4.04 (s, 2H), 3.59-3.52 (m, 2H), 2.68 (t, J=7.0 Hz, 2H), 2.16-2.09 (m, 1H), 1.16-1.05 (m, 4H); APCI MS m/z 365 [M+H]+.
