Participants

Reaction Steps

A solution of 8.5 g. of 1,3-dihydro-3-hydroxy-1'-methyl-3-phenylspiro[isobenzofuran-1,4'-piperidine], Example 1, in 150 ml. of tetrahydrofuran is added dropwise in 30 minutes to a stirred suspension of 2.0 g. of lithium aluminum hydride in 150 ml. of anhydrous tetrahydrofuran. The mixture is stirred at room temperature for 30 minutes and at 50° for 1 hour, cooled, diluted cautiously with water, and extracted with chloroform. The chloroform solution is dried over potassium carbonate and concentrated to a solid. Recrystallization from benzene gives colorless crystals, m.p. 190°-191° of 4-hydroxy-4-(α-hydroxy-α-phenyl-2-tolyl)-1-methylpiperidine.
