Reaktionsschritte
N-(2-ethylhexyl) cyanoacetamide (60.4 g., 0.30 mole), 4-methoxy-3-butene-2-one (60.0 g., 0.60 mole), methylcello-solve (250 ml.) and 1,4-diazobicyclo [2.2.2.] octane (6.0 g.) are heated at reflux for 4 hours. Additional 4-methoxy-3-butene-2-one (30 g.) is added and reflux is continued for another 2 hours. The solvent is removed in vacuo to give an oil. The oil is dissolved in methylene chloride and extracted first with 2N--HCl (150 ml.) and then with water (2 × 250 ml.). The organic layer is dried over sodium sulfate, filtered and evaporated to dryness to give a 90% yield of crude product which is characterized by nmr and ir analysis.
