Reaction Steps

0.50 g Raney nickel are added to a solution of 3.50 g (13.4 mmol) 5-nitro-1-(2-pyrrolidin-1-yl-ethyl)-1H-indazole in 50 mL EtOAc and the reaction mixture is stirred for 20 h at RT at 1.4 bar H2. After filtration the solvent is eliminated i.vac. The product is further reacted without any more purification.
