実験手順

HATU (0.092 g, 0.241 mmol) was added to a solution of 3-{[3-(aminomethyl)-6-chloro-2-fluorophenyl]oxy}-5-chlorobenzonitrile (0.050 g, 0.161 mmol), 5-methyl-2H-1,2,3-triazole-4-carboxylic acid (0.022 g, 0.177 mmol) and DIPEA (0.042 mL, 0.241 mmol) in DMF (2 mL). The resulting solution was stirred overnight. The reaction mixture was partitioned between water and EtOAc. The organic layer was separated, dried over MgSO4 and evaporated to a residue. Purification was accomplished by reverse-phase HPLC (water/acetonitrile with 0.1% TFA) to afford the title compound (0.0191 g, 28%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 10.51 (s, 1H), 7.79 (d, 1H), 7.69 (t, 1H), 7.46-7.51 (m, 2H), 7.44 (d, 1H), 7.30 (t, 1H), 4.36 (d, 2H), 2.15 (s, 3H). LCMS: m/z 420.0 (M+1).
