Reaction Steps

Boranedimethylsulphide complex (3 ml) was added dropwise under nitrogen over a period of 20 minutes to a solution of 1-dimethylamino-1-[1-(4-tolyl)cyclobutyl]pentan-2-one (1.85 g preprared as described in Example 16) in tetrahydrofuran (20 ml) and the resulting mixture stirred for 3 days at ambient temperature. The mixture was cooled to 0° C. and water (25 ml) and then 5N hydrochloric acid (25 ml) added. The mixture was basified and the tetrahydrofuran removed by evaporation. The residue was extracted with ether and the extracts washed with water, dried, filtered and evaporated to give an oil which was dissolved in petroleum ether (b.p. 80°-100° C.) and purified on a column packed with magnesia-silica gel sold under the trade name Florisil using petroleum ether (b.p. 80° to 100° C.) as eluant. The eluate was evaporated to give an oil which was distilled (215° C./1.5 mm Hg) to give 1-dimethylamino-1-[ 1-(4-tolyl)cyclobutyl]pentan-2-ol.
