1-Amino-N-phenyl-1H-pyrrole-2-carboxamide (500 mg, 2.48 mmol), (S)-1-(tert-butoxycarbonyl)-4,4-difluoropyrrolidine-2-carboxylic acid (687 mg, 2.73 mmol), HATU (1.04 g, 2.73 mmol) and diisopropylethylamine (476 μl, 2.73 mmol) were dissolved in a mixture of 6 mL of dichloromethane and 6 mL of DMF and stirred at room temperature overnight. The dichloromethane was removed under vacuum and 25 mL of water were poured over the remaining solution. A precipitated appeared and the suspension was stirred overnight. The solid was filtered and washed with water to furnish 1.05 g (97% yield) of the title compound.
