Procedure

To 2.71 g (13.7 mmol) of 1-(4-Chlorophenyl)piperazine and 3.58 g (12.5 mmol) of (5-Azidomethyl-4-chloro-3-trifluoromethyl-pyrazol-1-yl)-acetic acid in 40 mL of anhydrous dimethylformamide was added 4.36 mL (31.2 mmol) of triethylamine. The solution was cooled to 0° C., and 5.21 g (13.7 mmol) of O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU) was added. After 2 hours the reaction was diluted with two volumes of water, and the solvent was decanted away from the resulting oil. The oil was crystallized by dissolving in methanol and adding water in small portions. The product was isolated as a white solid by filtration: 1H NMR (DMSO-d6, 400 MHz) 7.23 (d, 2H), 6.97 (d, 2H), 5.48 (s, 2H), 4.62 (s, 2H), 3.60 (m, 4H), 3.24 (m, 2H), 3.12 (m, 2H) ppm; MS (ES) M+H expected=462.1, found=462.0.
