HATU (0.061 g, 0.16 mmole) was added to a DMF (2 ml) solution of 3-{[3-(aminomethyl)-6-chloro-2-fluorophenyl]oxy}-5-chlorobenzonitrile (0.050 g, 0.16 mmole) and 3-chloro-1H-pyrrole-2-carboxylic acid (0.023 g, 0.16 mmole) in DMF. DIPEA (0.021 g, 0.16 mmole) was added and the solution stirred for 2 h. The mixture was partitioned between EtOAc and water. The organic layer was separated and washed with 15% NaHCO3 and dried over MgSO4 and the EtOAc evaporated. The residue was purified on silica with EtOAc and Hexanes to afford the title compound (0.0187 g, 26%) as a white solid. 1H NMR (400 MHz, Acetone-d6): δ ppm 10.93 (br. s., 1H), 7.62-7.67 (m, 1H), 7.56-7.62 (m, 1H), 7.37-7.48 (m, 4H), 7.02 (t, 1H), 6.23 (t, 1H), 4.72 (d, 2H). MS: m/z 438.1 (M+1).
