Reaction Steps

N-cyclobutanoyl-N′-[5-(4-Chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazole-3-carbonyl]-hydrazine (0.14 g, 0.29 mmol) was added to a microwave reactor containing Lawesson's reagent (0.18 g, 0.44 mmol) in 1,4-dioxane (3 mL). The capped reactor was placed into a microwave reactor and the mixture was heated at 180° C. for 15 min, and the process was repeated one more time. The reaction mixture was then purified by preparative HPLC to provide the title compound (60 mg, 0.16 mmol, 43%) as yellow solid.
