Procedure

To a solution of methyl 3-chloro-4-[(ethylamino)carbonyl]-1H-pyrrole-2-carboxylate (0.03 g, 0.130 mmol) in THF (3 mL) and water (1 mL) was added lithium hydroxide (0.031 g, 1.301 mmol). The reaction mixture was stirred overnight at 35° C. The solvent was evaporated and the resulting solid placed under high vacuum. To the intermediate mixture was added DMF (1 mL), HATU (0.059 g, 0.156 mmol), DIPEA (0.034 ml, 0.195 mmol) and 3-{[3-(aminomethyl)-6-chloro-2-fluorophenyl]oxy}-5-chlorobenzonitrile (0.040 g, 0.130 mmol). The solution was stirred for 2 h at RT. Purification was accomplished by HPLC. The desired fractions were neutralized with saturated sodium bicarbonate, extracted with EtOAc (3×5 mL), the organic layers combined, dried over sodium sulfate, filtered and evaporated to afford 3-chloro-N2-({4-chloro-3-[(3-chloro-5-cyanophenyl)oxy]-2-fluorophenyl}methyl)-N4-ethyl-1H-pyrrole-2,4-dicarboxamide (0.0033 g, 5% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6): δ ppm 12.15 (br. s., 1H) 8.14 (s, 1H) 7.83 (d, 2H) 7.44-7.54 (m, 4H) 7.37 (s, 1H) 4.57 (d, 2H) 3.20 (dd, 2H) 1.08 (t, 3H). MS: m/z 509.2 (M+1).
