Sodium borohydride → (3,5-Bis-trifluoromethylphenyl)(3-methyl-4-nitrophenyl)methanol

Participants

Reaction Steps

Sodium borohydride (0.12 g) was added to a solution of 3′,5′-bis-trifluoromethyl-3-methyl-4-nitrobenzophenone (2.2 g) in methanol (10 ml) in an ice bath. After stirring at room temperature for 1 hour, and diluting with ethyl acetate, it was washed with water and a saturated salt solution. After drying over anhydrous magnesium sulfate, the solvent was distilled off and the residue was purified by silica gel column chromatography to obtain (3,5-bis-trifluoromethylphenyl)(3-methyl-4-nitrophenyl)methanol (1.6 g).
