Procedure
2,2,2-Trifluoro-1-[4-fluoro-3-(trifluoromethyl)phenyl]ethanamine (0.82 g, 3.05 mmol) was dissolved in N,N-dimethylformamide (6 ml), and 6-chloro-5-(ethoxycarbonyl)-1H-indole-2-carboxylic acid (0.82 g, 3.05 mmol), N-[(1H-benzotriazol-1-yloxy)(dimethylamino)methylene]-N-methylmethanaminium hexafluorophosphate (1.16 g, 3.05 mmol) and 4-methylmorpholine (0.92 g, 9.10 mmol) were added. The reaction mixture was stirred at room temperature for 16 h and then water was added. The aqueous phase was extracted three times with ethyl acetate, dried over sodium sulphate, adsorbed on silica gel and chromatographed with cyclohexane/ethyl acetate (4/1). 1.29 g (65% of theory) of ethyl 6-chloro-2-({2,2,2-trifluoro-1-[4-fluoro-3-(trifluoromethyl)phenyl]ethyl}carbamoyl)-1H-indole-5-carboxylate were obtained.
