Reaction Steps

Methanesulfonyl chloride (2 eq., 0.01 mL, 0.15 mmol) was added to tert-Butyl 4-[5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazole-3-amido]piperidine-1-carboxylate (1 eq., 35 mg, 0.076 mmol) and triethyamine (3 eq., 0.03 mL, 0.227 mmol) in tetrahydrofuran (2 mL). The reaction was stirred 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 5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-N-(1-methanesulfonyl-piperidin-4-yl)-4-methyl-1H-pyrazole-3-carboxamide (36 mg, 87%). 1H NMR (300 MHz, CHLOROFORM-d) d ppm 1.53-1.78 (m, 2H) 2.06-2.22 (m, 2H) 2.37 (s, 3H) 2.67-3.00 (m, 5H) 3.82 (d, J=12.24 Hz, 2H) 4.01-4.17 (m, 1H) 6.88 (d, J=8.01 Hz, 1H) 7.07 (s, 2H) 7.19-7.36 (m, 4H) 7.43 (d, J=1.70 Hz, 1H).
