Procedure

A well stirred mixture of 2,6-dichloro-4-(ethylcarbamoyl)benzoic acid (84.6 mg, 0.42 mmol), 1-hydroxy-7-azabenzotriazole (77 mg, 0.57 mmol), N,N-dimethyl aminopyridine (22 mg, 0.11 mmol) and 2-(1H-7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyl uronium hexafluorophosphate methanaminium (216 mg, 0.57 mmol) in N,N-dimethylaniline was treated with N-(1H-pyrrolo[3,2-c]pyridin-4-yl)cyclopropanecarboxamide (100 mg, 0.38 mmol) and N,N-diisopropylethylamine (0.1 ml, 0.95 mmol). The reaction was stirred overnight at room temperature. The contents were diluted with water and extracted with ethyl acetate. The combined organic portion was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated. The crude product was purified by silica gel column chromatography using methanol in dichloromethane (3%) as eluent to yield 3,5-dichloro-4-({4-[(cyclopropylcarbonyl)amino]-1H-pyrrolo[3,2-c]pyridin-1-yl}carbonyl)-N-ethylbenzamide (45 mg, 26%) as an off white solid.
