Procedure

A solution of 3.97 grams (0.025 mole) of 3-cyanomethylbenzo[b]furan in 200 milliliters of diethyl ether was slowly added to a refluxing suspension of 3.84 grams (0.1 mole) of lithium aluminum hydride in 400 milliliters of ether and the mixture was heated 3 hours, then cooled and water was slowly added. The suspension was filtered and the filtrate was evaporated to obtain an oily product, the hydrochloride salt of which has m.p. 183°-185° C.
