Dissolve 28 g of 2-(p-chlorobenzylidene)-1-methylpyrrolidine in 250 ml of methanol and hydrogenate the thus-obtained solution with Raney nickel as catalyst. Filter the catalyst from the hydrogenated product and then concentrate the filtrate to obtain 22.7 g of the title compound having a boiling point of 75° at 0.005 millimeters (mm) of Hg (yield: 81% of theory). The picrate (from ethanol) melts at 149°.
