Versuchsvorschrift

1-{[5-(4-Chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazol-3-yl]carbonyl}-4-phenylpiperidin-4-amine (1 eq, 36.5 mg, 0.068 mmol), methanesulfonyl chloride (2 eq, 0.01 mL, 0.135 mmol), and triethylamine (3 eq, 0.03 mL, 0.203 mmol) was stirred in tetrahydrofuran for 16 h. The reaction was concentrated in vacuo. The crude reaction material was then purified by silica gel column chromatography using 0-100% ethyl acetate/hexane to yield pure N-(1-{[5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazol-3-yl]carbonyl}-4-phenylpiperidin-4-yl)methanesulfonamide (27 mg, 65%). 1H NMR (300 MHz, CHLOROFORM-d) d ppm 2.18 (d, J=4.52 Hz, 6H) 2.21-2.37 (m, 2H) 2.39-2.61 (m, 2H) 3.65 (t, J=10.69 Hz, 1H) 3.86 (t, J=10.93 Hz, 1H) 4.07-4.20 (m, 2H) 4.29 (d, J=13.75 Hz, 1H) 5.30 (s, 1H) 7.03-7.11 (m, 2H) 7.15-7.21 (m, 1H) 7.21-7.38 (m, 4H) 7.38-7.47 (m, 2H) 7.47-7.55 (m, 2H).
