HCID 234479053-Phenyl-N-[3-[4-[2-(2,2,2-trifluoroethoxy)phenyl]-1-piperazinyl]propyl]isoxazole-4-carboxamideYield 88%

Procedure

The title compound was prepared according to the procedure described in Example 8, but substituting compound 15B for Compound 8D and Compound 12B for Compound 8B. Purification by flash chromatography (ethyl acetate-2 N ammonia in methanol 95:5) yielded the title product (88%). M.p. 94.5-95.6° C.
