Procedure

To a stirred mixture of (2R)-2-benzyl-1-[3,5-bis(trifluoromethyl)benzoyl]piperazine (0.3 g) and 2-(1H-indol-3-yl)acetic acid (0.13 g) in dichloromethane (8 ml) containing triethylamine (0.25 ml) was added 2-chloro-1-methylpyridinium iodide (0.22 g) at room temperature under nitrogen atmosphere. After being stirred for 5 hours, the reaction mixture was diluted with dichloromethane and washed with 0.1N hydrochloric acid, aqueous saturated sodium bicarbonate solution and brine, and dried over magnesium sulfate. After removal of the solvent, the residue was purified by column chromatography on silica gel using chloroform-methanol (50:1) as eluent to give (2R)-2-benzyl-1-[3,5-bis(trifluoromethyl)benzoyl]-4-[2-(1H-indol-3-yl)acetyl]piperazine (0.34 g) as a white powder.
