実験手順

450 mg of 3-(3-cyanophenyl)-1,6-dimethyl-1,9-dihydro-2H-pyrido[2,3-b]indol-2-one, 10 ml of AcOH, 20 ml of pyridine, 2.6 g of sodium hypophosphite and 434 mg of Raney Ni are mixed and then the mixture is heated at 60° C. for 4 hours. The reaction medium is filtered and the filtrate is evaporated; the residue is taken up in 50 ml of AcOEt/CH2Cl2 (1/1; v/v) and the organic phase is washed with water, dried and evaporated to produce the expected compound, M.p.=280° C.
