HATU (0.061 g, 0.161 mmol) was added to a solution of 5-(aminocarbonyl)-3-chloro-1H-pyrrole-2-carboxylic acid (0.030 g, 0.161 mmol), 3-{[3-(aminomethyl)-6-chloro-2-fluorophenyl]oxy}-5-chlorobenzonitrile (0.050 g, 0.161 mmol), and DIPEA (0.028 mL, 0.161 mmol) in DMF (2 mL). This solution was stirred overnight at RT. The reaction mixture was partitioned between water and EtOAc. The organic layer was washed with a 15% solution of Na2CO3, dried over MgSO4, filtered and evaporated. Purification was accomplished by silica gel column chromatography (EtOAc/hexanes) to afford the title compound (0.023 g, 28%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 12.08 (br. s., 1H), 8.48-8.74 (m, 1H), 7.72-7.98 (m, 2H), 7.27-7.62 (m, 5H), 6.83 (d, 1H), 4.48 (d, 2H). LCMS: m/z 481.0 (M+1).
