Reaction Steps

A mixture of 3-{[3-(aminomethyl)-6-bromo-2-fluorophenyl]oxy}-5-chlorobenzonitrile (0.050 g, 0.141 mmol), 4-bromo-2-methyl-1H-imidazole-5-carboxylic acid (0.029 g, 0.141 mmol), HATU (0.064 g, 0.169 mmol) and DIPEA (0.029 mL, 0.169 mmol) in DMF (1 mL) was stirred at RT overnight. The reaction mixture was extracted with EtOAc and water. The organic layer was dried over sodium sulfate and concentrated. The residue was purified by preparative LCMS (acetonitrile:water with 0.1% formic acid) to give the title compound (15 mg, 19.6%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.17 (br. s., 1H), 7.77 (s, 1H), 7.57 (d, 1H), 7.45 (s, 1H), 7.40 (d, 1H), 7.25 (t, 1H), 4.18-4.59 (m, 2H), 2.21 (s, 3H). ES MS: m/z 541, 543.
