Versuchsvorschrift

21.2 g (0.0965 mol) of the 1-(3'-nitro-4',6'-dimethylphenyl)-azetidin-2-one obtained according to a) are hydrogenated in 210 ml of methanol with 2 g of Raney nickel at 30°-35° under normal pressure. The reaction solution is filtered and evaporated. Recrystallisation of the crude product from methanol gives 16.6 g (90%) of crystals having a melting point of 123°-124°.
