Reaction Steps

A solution of 1-benzyl-3-(3-cyanopropyl)indazole (100 mg, 0.35 mM) in ethanol (10 ml) was stirred at room temperature and Raney nickel (approx. 100 mg, wet weight) was added. The resulting suspension was warned to 65° C. and hydrazine hydrate (0.1 ml, 87 mg) added carefully. The mixture was stirred at 70° C. for a further 2 hr then cooled and filtered through celite. Solvent was removed in vacuo and the residue purified by chromatography on silica (chloroform/methanol 9:1) to give the title product as a clear oil (25 mg, 26%).
