4-Isoxazolecarbonyl chloride, 3-(2-chlorophenyl)-5-methyl- → 3-(2-Chlorophenyl)-5-methyl-n-[3-[4-[2-(2,2,2-trifluoroethoxy)phenyl]-1-piperazinyl]propyl]-isoxazole-4-carboxamide

Participants

Reaction Steps

The title compound was synthesised according to the procedure described in Example 8 but using 3-(2-chlorophenyl)-5-methylisoxazole-4-carbonyl chloride instead of the crude 3-(4-fluorophenyl)isoxazole-4-carbonyl chloride and Compound 12B instead of Compound 8B. Washing the reaction mixture with 2 N sodium hydroxide, followed by the usual work-up and purification by flash chromatography (chloroform-2 N ammonia in methanol 100:3) afforded the title compound (67.2%) as an oil.
