Reaction Steps

To a stirred suspension of 0.53 g. of lithium aluminum hydride in 50 ml. of tetrahydrofuran is added dropwise a solution of 2.20 g. of 1'-acetyl-1,3-dihydro-3-phenylspiro[isobenzofuran-1,4'-piperidine] (Example 80), in 50 ml. of tetrahydrofuran. The mixture is heated under reflux for 2 hours, cooled, quenched cautiously with water, and extracted with ether. The ether solution is dried over sodium sulfate and concentrated to a solid. Recrystallization from chloroform provides colorless crystals, m.p. 113°-115°.
