Procedure
A mixture of (2R)-1-[3,5-bis(trifluoromethyl)-benzoyl]-2-(1H-indol-3-ylmethyl)piperazine (120 mg), 4-chloromethyl-2-(2-methoxyethylcarbonylamino)thiazole (70 mg) and powdered sodium hydrogen carbonate (27 mg) in dry dimethylformamide was stirred for 5 hours and 20 minutes at 60° C. The reaction mixture was powered into water and the resulting precipitate was collected by filtration. The crude product was purified by column chromatography on silica gel eluting with a mixture of dichloromethane and methanol (30:1). The eluate was evaporated under reduced pressure and treated with 17.6% hydrogen chloride in ethanol (0.12 ml) to give (2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-2-(1H-indol-3-ylmethyl)-4-[[2-(3-methoxypropanoylamino)thiazol-4-yl]methyl]piperazine hydrochloride (140 mg).
