Reaction Steps

A solution of 4-(2,4-dichloro-phenyl)-1H-pyrazole-3-carboxylic acid (70 mg; 0.27 mmol), 4-(4-methyl-piperazin-1-yl)-benzylamine (62 mg; 0.3 mmol), EDAC (63 mg; 0.33 mmol) and HOBt (45 mg; 0.33 mmol) in 5 ml of DMF was stirred at room temperature for 48 hours. The reaction was evaporated and the residue partitioned between ethyl acetate and brine. The ethyl acetate layer was separated, dried (MgSO4), filtered, evaporated then dried further under vacuum to give 34 mg of 4-(2,4-dichloro-phenyl)-1H-pyrazole-3-carboxylic acid 4-(4-methyl-piperazin-1-yl)-benzylamide. (LC/MS: Rt 2.42 [M+H]+444).
