Reaction Steps

To a mixture of (2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-2-(3,4-dimethylbenzyl)piperazine (0.25 g) and 4-acetylbenzoic acid (0.09 g) in dichloromethane (8 ml) was added triethylamine (0.2 ml) at room temperature. 2-Chloro-1-methylpyridinium iodide (0.17 g) was added, and the mixture was stirred at room temperature for 2.5 hours. The resulting mixture was concentrated under reduced pressure and the residue was partitioned between ethyl acetate and water. The organic layer was washed with aqueous sodium bicarbonate solution and dried over magnesium sulfate. After evaporation of the solvent, the residue was purified by column chromatography using ethyl acetate--n-hexane (1:1) as an eluent to afford (2R)-4-(4-acetylbenzoyl)-1-[3,5-bis(trifluoromethyl)benzoyl]-2-(3,4-dimethylbenzyl)piperazine (0.31 g).
