Procedure

1-Amino-N-phenyl-1H-pyrrole-2-carboxamide (570 mg, 2.83 mmol), 2-(tert-butoxycarbonylamino)-3,3,3-trifluoropropanoic acid (826 mg, 3.40 mmol), HATU (1.29 g, 3.40 mmol) and N-methylmorpholine (685 μl, 6.23 mmol) were suspended in 20 mL of dichloromethane and stirred overnight. The reaction mixture was diluted with more dichloromethane and the solution was washed with water and brine, dried over magnesium sulphate, filtered and the solvent was removed in vacuum. The product was purified by reverse phase chromatography (C-18 silica from Waters®, water/1:1 acetonitrile-methanol as eluents [0.1% v/v formic acid buffered] 0% to 100%) to obtain the title compound in a 47% yield (562 mg) as a white solid.
