A mixture of N-(4-(2H-tetrazol-5-yl)phenyl)-4-(3-morpholinophenyl)pyrimidin-2-amine (0.20 g, 0.50 mmol), MeI (0.71 g, 5.0 mmol) and K2CO3 (0.35 g, 2.50 mmol) in acetone (5 mL) was stirred at room temperature overnight. The reaction mixture was diluted with water, extracted with EtOAc (3×). The combined organic solution was dried over anhydrous MgSO4 and concentrated in vacuo to give a solid. Purification of this material by column chromatography on silica gel (40% EtOAc/hexane) provided N-(4-(2-methyl-2H-tetrazol-5-yl)phenyl)-4-(3-morpholinophenyl)pyrimidin-2-amine as the major product. 1H NMR (DMSO-d6, 400 MHz) δ 10.00 (s, 1H), 8.60 (d, 1H), 8.05 (d, 2H), 8.00 (d, 2H), 7.78 (s, 1H), 7.65 (d, 1H), 7.50 (d, 1H), 7.42 (t, 1H), 7.18 (dd, 1H), 4.42 (s, 3H), 3.80 (m, 4H), 3.24 (m, 4H). MS (ESI) 415.13 (M+H).
