Reaction Conditions

Reaction Steps

A mixture of 2-(4-bromomethylphenyl)benzonitrile (12 g) and potassium phtalimide (15 g) in DMF (200 ml) was stirred at 70° C. for 5 hours. After addition of water, the mixture was extracted with methylene chloride. The extract was washed with water, dried and concentrated to dryness to give crystals. Recrystallization from ethyl acetate-isopropyl ether gave colorless crystals. To a suspension of the crystals in methanol (500 ml) was added hydrazine hydrate (10 ml) and the mixture was refluxed for 12 hours. After evaporation of the solvent, the residue was dissolved in ethyl acetate and the solution was washed with 1N-NaOH and water. The organic layer was dried and concentrated to dryness to give crystals (14.2 g, 93%).
