Versuchsvorschrift

The dioxime from Step 2 (30 g) is dissolved in ethyl alcohol (300 ml), saturated with ammonia gas and Raney nickel catalyst W-6 (2 g) added. The mixture is subjected to 700 psi hydrogen pressure and heated at 70° for 3 hours. The catalyst is removed by filtration and 220 ml of ethanol is removed by distillation. The pale yellow precipitate is filtered and dried. Yield 28 g (91% of theory) mp 123°-7°.
