1,2-Dichloroethane → N-[(3R)-1-phenylpiperidin-3-yl]-3-(pyridin-4-yl)-1-trityl-1H-indazole-5-carboxamide

Participants

Reaction Steps

A solution of 3-(pyridin-4-yl)-1-trityl-1H-indazole-5-carboxylic acid (97 mg, 0.20 mmol), (3R)-1-phenylpiperidin-3-amine (120 mg, 0.48 mmol), EDC (0.08 g, 0.4 mmol), HOBt (0.07 g, 0.5 mmol) and DIPEA (400 μl, 2.3 mmol) in DMF (2 ml) was stirred at room temperature for 1.5 hours. The reaction mixture was concentrated in vacuo to provide crude N-[(3R)-1-phenylpiperidin-3-yl]-3-(pyridin-4-yl)-1-trityl-1H-indazole-5-carboxamide, which was used as-is without further purification. LCMS calc'd for C43H38N5O [M+H]+=640; found 640.
