Procedure
A 1M solution of diisobutylaliminohydride in hexane (200 ml) was added under nitrogen to a solution of 1-phenyl-1-cyclobutane carbonitrile (31.4 g) in ether (100 ml) at a temperature below -30° C. The temperature was maintained below 0° C. for thirty minutes and 5N hydrochloric acid (200 ml) at a temperature of -10° C. added. The reaction mixture was washed with petroleum ether (b.p. 60°-80° C.) and then warmed to 40° C. The reaction mixture was extracted with petroleum ether (b.p. 60°-80° C.) and the extract dried and evaporated to yield 1-phenyl-1-cyclobutane-carbaldehyde as an oil.
