Dissolve 10 g of 2-(α-cyano-4-nitrobenzylidene)-1-methylpyrrolidine in ethanol and then reduce it with platinum/hydrogen. After completion of hydrogen uptake, filter the catalyst from the hydrogenated product, distil off the solvent and recrystallize the residue from 50 ml of ethanol to obtain 5.5 g of the title compound as light-brown crystals of m.p. 116° to 118°.
