Versuchsvorschrift

To 38 mg (0.20 mmol) of 1-(2,5-Dimethylphenyl)piperazine and 53 mg (0.22 mmol) of (4-Chloro-5-methyl-3-trifluoromethyl-pyrazol-1-yl)-acetic acid in 1.6 mL of anhydrous dimethylformamide was added 62 mg (0.6 mmol) of triethylamine, followed by 84 mg (0.22 mmol) of O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU). After 6 hours, the reaction was partitioned between ethyl acetate and water, and the phases were separated. The aqueous phase was back-extracted once with ethyl acetate, and the combined ethyl acetate phases were washed once each with 0.5M pH=7 phosphate buffer, water, 1M NaOH, water, brine. The ethyl acetate phase was then dried over Na2SO4, filtered, and concentrated to a residue in vacuo. The residue was dissolved in a minimum volume of 5M HCl in isopropanol, and was precipitated by diluting the solution with ethyl acetate. The product was isolated by filtration to give a white solid: 1H NMR (DMSO-d6, 400 MHz) 7.07 (d 1H), 6.90 (s, 1H), 6.82 (d, 1H), 5.39 (s, 2H), 3.66 (m, 4H), 2.98 (m, 2H), 2.89 (m, 2H), 2.26 (s, 3H), 2.24 (s, 3H), 2.20 (s, 3H) ppm; MS (ES) M+H expected=415.1, found 415.1.
