Procedure

A solution of 3,6-bis(t-butyldimethylsiloxy)-7,8-didehydro-4,5-epoxy-17-cyanoethylmorphinan (200 mg, 0.36 mmol) in dry ethyl ether (5 ml) was added dropwise to a suspension of lithium aluminum hydride (0.13 g, 3.6 mmol) in dry ethyl ether (5 ml). After stirring for 3 h at room temperature the reaction mixture was added wet ether followed by 10% sodium hydroxide (1.5 ml). The solution was filtered, and the white precipitate was washed with ether. The ether layer was evaporated under reduced pressure to give the amine as a clear liquid (yield=0.2 g, 99%).
