Procedure

The nitrile (6.41 g) was dissolved in 300 ml of tetrahydrofuran and, 4.06 g lithium aluminum hydride was added, with stirring. The suspension was heated at reflux for 2 hr and ethyl acetate, water, aqueous sodium hydroxide solution and water were added. The suspension was filtered and the filtrate was concentrated. The residue was triturated with ether and the solid was recrystallized from methanol to give 0.64 g (18%) of the product, mp 260°-263° C. (dec.).
