Benzyl 3-(5-cyano-4-(2,6-difluorophenyl)-N-isopropyl-1H-1,2,3-triazole-1-carboxamido)benzoate → 3-(5-cyano-4-(2,6-difluorophenyl)-N-isopropyl-1H-1,2,3-triazole-1-carboxamido)benzoic acid

Participants

Reaction Steps

To a solution of benzyl ester (6) (1.0 equiv) in methanol (0.1 M) under argon was added 5% Pd/C (0.1 equiv) and the inert atmosphere was replaced with hydrogen. The resulting mixture was stirred at rt for 30 min, filtered through a pad of Celite with aid of methanol and the resulting filtrate concentrated in vacuo. The residue was purified by preparative HPLC (0.1% formic acid in acetonitrile/water) to afford 3-(5-cyano-4-(2,6-difluorophenyl)-N-isopropyl-1H-1,2,3-triazole-1-carboxamido)benzoic acid (7) as a lyophilized powder.
