Procedure

A mixture of (2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-4-(4-chloro-2-butynyl)-2-(3,4-dimethylbenzyl)piperazine (150 mg), (3S)-3-ethylmorpholine hydrochloride (47 mg) and powdered potassium carbonate (117 mg) in dry N,N-dimethylformamide (1 ml) was stirred at 50° C. for 1.5 hours. The reaction mixture was poured into water (10 ml) and extracted with ethyl acetate. The extract was washed with brine and dried over magnesium sulfate. After evaporation of the solvent, the obtained residue was purified by column chromatography on silica gel using ethyl acetate as eluent. The obtained product was dissolved in ethyl acetate and treated with 4N hydrogen chloride in ethyl acetate to give (2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-4-[4-((3S)-3-ethylmorpholino)-2-butynyl]-2-(3,4-dimethylbenzyl)piperazine dihydrochloride (177 mg).
