Procedure

A mixture of 4.0 g. of 1,3-dihydrospiro[isobenzofuran-1,4'-piperidine]-3-one, 6.4 g. of 4-chloro-1,1-di(4-fluorophenyl)butane, 10 g. of potassium carbonate, and 25 ml. of 1-butanol is heated under reflux for 48 hours and filtered. The filtrate is diluted with water and extracted with benzene. The benzene solution is dried over potassium carbonate and concentrated to an oil, 1,3-dihydro-1'-[4,4-di(4-fluorophenyl)butyl]spiro[isobenzofuran-1,4'-piperidine]-3-one. The oil is converted to a crystalline hydrochloride salt, m.p. 182°-183° (from benzene).
