Reaction Steps

To a stirred solution of crude 2-(4-((2-(3-chlorophenyl)-6-ethylpyrimidin-4-yl)methyl)phenyl)acetyl chloride (˜0.20 mmol) in dichloromethane (8 mL) at 0° C. was added n-propylamine (0.082 mL, 1.00 mmol) followed by diisopropylethylamine (0.17 mL, 1.00 mmol). After stirring for 2.5 h, the reaction mixture was diluted with dichloromethane (50 mL) and water (5 mL). The mixture was acidified with 2N aqueous HCl until pH˜5. The organic layer was washed with saturated sodium chloride (5 mL), dried over sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by chromatography on silica using hexanes/ethyl acetate (10:0 to 1:1) as eluent followed by preparative HPLC (water/acetonitrile with 0.05% TFA) to afford the title compound (0.044 g, 55%) as a white solid. MW=407.94. M.p. 123-125° C. 1H NMR (DMSO-d6, 500 MHz) δ 8.37-8.31 (m, 2H), 7.98-7.93 (m, 1H), 7.60 (dt, J=8.5, 2.0 Hz, 1H), 7.55 (t, J=7.5 Hz, 1H), 7.28 (d, J=8.0 Hz, 2H), 7.24 (s, 1H), 7.20 (d, J=8.0 Hz, 2H), 4.09 (s, 2H), 3.34 (s, 2H), 2.97 (q, J=6.0 Hz, 2H), 2.77 (t, J=7.5 Hz, 2H), 1.43-1.34 (m, 2H), 1.26 (t, J=7.5 Hz, 3H), 0.81 (t, J=7.5 Hz, 3H); APCI MS m/z 408 [M+H]+.
