Methanol → 3-(5-(4-Chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazol-3-yl)-5-cyclopentyl-1H-1,2,4-triazole

A solution of 5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazole-3-carbonitrile (300 mg, 0.83 mmol), cyclopentanecarbohydrazide (116 mg, 0.90 mmol) and potassium carbonate (57 mg, 0.41 mmol) dissolved in 1-butanol (2 ml) was placed in a sealed tube, stirred at room temperature for 10 minutes and then refluxed at 150° C. for 1 day. The mixture was cooled down to room temperature and methanol (4 ml) was added thereto, followed by filtering. The filtrate was purified by reverse phase preparative HPLC, to obtain the title compound as white solid.
