Versuchsvorschrift

A solution of 3.97 g (0.025 mole) of 3-cyanomethylbenzo[b]furan in 200 mL of diethyl ether was slowly added to a refluxing suspension of 3.84 g (0.1 mole) of lithium aluminum hydride in 400 mL of ether. The reaction was heated 3 hrs., cooled and water was slowly added. The suspension was filtered through a pad of filter aid and the filtrate was evaporated to give 3.2 g of oily product. The hydrochloride salt has m.p. 183°-185° C.
