2-(2-Cyclopropyl-acetyl)-5,5-dimethyl-cyclohexane-1,3-dione (111.1 mg, 0.5 mmol) and 4-cyanophenylhydrazine hydrochloride (84.8 mg, 0.5 mmol, 1.0 eq) were suspended in 4 mL of 3:1 EtOH:AcOH and microwaved at 100° C. for 10 minutes. The solvent was removed in vacuo and the resultant residue purified by column chromatography to yield 81.8 mg (51% yield) of 4-(3-Cyclopropylmethyl-6,6-dimethyl-4-oxo-4,5,6,7-tetrahydro-indazol-1-yl)-benzonitrile as an off-white powder.
