Participants

Reaction Steps

2,2,2-Trifluoro-1-[3-fluoro-3-(trifluoromethyl)phenyl]ethanamine (726 mg, 2.98 mmol) was dissolved in N,N-dimethylformamide (10 ml), and 5-{[(tert-butoxycarbonyl)amino]methyl}-6-methyl-1H-pyrrolo[2,3-b]pyridine-2-carboxylic acid (730 g, 2.39 mmol), N-[(1H-benzotriazol-1-yloxy)(dimethylamino)methylene]-N-methylmethanaminium hexafluorophosphate (907 mg, 2.39 mmol) and 4-methylmorpholine (725 mg, 7.17 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 and the extract was dried over sodium sulphate, adsorbed on silica gel and chromatographed with ethyl acetate. 420 mg (33% of theory) of tert-butyl {[6-methyl-2-({2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]ethyl}carbamoyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]methyl}carbamate were obtained. HPLC-MS: log P=3.49; mass (m/z): 531.2 (M+H)+; 1HNMR (D6-DMSO): δ 1.40 (s, 9H), 3.30 (s, 3H), 4.20 (m, 2H), 6.29-6.32 (m, 1H), 7.35 (s, 1H), 7.71 (m, 1H), 7.82-7.84 (m, 1H), 8.03 (d, 1H), 8.17 (s, 1H), 9.43 (m, 1H).
