Participants

Reaction Steps

A 1M aqueous sodium hydroxide solution (0.74 ml) and a 30% aqueous hydrogen peroxide solution (0.56 ml) were added to a solution of 3-chloro-4-[(1S)-1-{4-methyl-5-[2-(trifluoromethyl)phenyl]-4H-1,2,4-triazol-3-yl}ethoxy}benzonitrile (200 mg) in ethanol (6 ml) at 0° C., followed by stirring at room temperature for 3 hours. The reaction solution was added to a mixture of water and chloroform, followed by separation operation, and the organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was washed with diisopropylether, to obtain, as a colorless solid, 3-chloro-4-[(1S)-1-{4-methyl-5-[2-(trifluoromethyl)phenyl]-4H-1,2,4-triazol-3-yl}ethoxy}benzamide (135 mg).
