Reaction Steps

A solution of 3-(5-(4-Chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazol-3-yl)-5-cyclopentyl-1H-1,2,4-triazole (400 mg, 0.82 mmol), iodomethane (0.19 ml, 2.5 mmol) and potassium hydroxide (138 mg, 2.5 mmol) dissolved in methanol (3 ml) was placed in a round bottom flask, stirred at room temperature for 1 day. After evaporation of the volatile solvent, the crude residue was purified by column chromatography to obtain the title compound (330 mg, 80%) as white solid.
