Carbon tetrabromide → 3-(Bromomethyl)-5-(trifluoromethyl)benzonitrile

Participants

Reaction Steps

To a solution (10 ml) of 3-hydroxymethyl-5-trifluoromethylbenzonitrile (1.00 g) and carbon tetrabromide (1.81 g) in dichloromethane was added triphenylphosphine (1.37 g) with stirring under ice-cooling, and the mixture was continuously stirred for 30 min. The reaction solution was concentrated and the obtained residue was purified by column chromatography (n-hexane:ethyl acetate=9:1) to give the title compound (1.11 g, 84%).
