Procedure
A solution of 7.7 g. of 1'-benzyl-1,3-dihydro-3-phenylspiro[isobenzofuran-1,4'-piperidine] (Example 4), 40 ml. of benzene and 2.5 ml. of ethyl chloroformate is heated under reflux for 18 hours and concentrated to a solid. Recrystallization from cyclohexane provides colorless crystals, m.p. 115°-119°.
