Procedure
A solution of acid 7 (0.3 g, 1 mmol), HOBT-NH3 (0.3 g, 2 mmol), TBTU (0.64 g, 2 mmol), DIEA (1 mL, 6 mmol) in DMF (4 mL) was stirred at rt for 6 h. The reaction mixture was poured into water and the aqueous phase was extracted (×3) with EtOAc. The organic phase was washed with 1N NaOH, then with water, brine, dried (Na2SO4) and concentrated. The crude material was purified by silica gel chromatography (DCM/MeOH 12:1) to yield 2-cyclohexyl-5-pyridin-4-yl-1H-pyrrole-3-carboxylic acid amide (0.12 g, 43%) as a white solid.
