실험 절차

4-(2-Chloro-5-trifluoromethylbenzoyl)-1-butanol, prepared as described in EXAMPLE 17, was converted to the corresponding methanesulfonate by the method described in EXAMPLE 2. Treatment with spiro[isobenzofuran-1(3H),4'-piperidine] according to the method described in EXAMPLE 2 gave 1'-[4-(2-chloro-5-trifluoromethylbenzoyl)-1-butyl]-spiro[isobenzofuran-1(3H),4'-piperidine]. Conversion to the corresponding hydrazone and ring closure according to the method described in EXAMPLE 17 gave the title compound, 18, mp: 146-47° C.
