Reaction Conditions

Reaction Steps

A solution of [4-(4,6-diphenylpyrimidin-2-yl)-phenyl]methanol, 0.38 g (1.11 mmol), triethylamine, 0.34 mL (2.45 mmol), and 6 mL of methylene chloride was cooled to 0° C. via ice-water bath. Methanesulfonyl chloride, 0.10 mL (1.23 mmol) was added dropwise over minutes. The solution stirred for 2 h at 0° C. The solution was quenched with 20 mL of water and diluted with 20 mL of ethyl acetate. The organic layer was washed with water, sat. aq. NaCl, and dried (MgSO4). After the solution was concentrated, the residue was recrystallized with EtOAc-Heptane (1:2) to afford the desired product in 0.44 g (95%) as a yellow solid. 1H NMR (DMSO-d6) 8.77 (d, 2H, J=9.0), 8.44-8.41 (m, 4H), 8.30 (s, 1H), 7.68-7.61 (m, 8H), 5.37 (s, 2H), 3.11 (s, 3H).
