Reaction Steps

The product (0.01 mol) of Stage 2 was added portionwise to a suspension of lithium aluminium hydride (0.005 mol) in diethyl ether (10 ml; dried over sodium) to maintain refluxing. The ethereal solution was refluxed for a further four hours; the excess lithium aluminium hydride was quenched with water (20.0 ml) and the mixture acidified with concentrated sulphuric acid. The ethereal layer was washed with water (4×25 ml) and dried over anhydrous sodium sulphate. Removal of the ether gave an oil which solidified on standing. Recrystallisation from methylene chloride/petroleum ether gave the title compound as a white solid, m.p. 93°-94°.
