Reaction Steps

25 g of intermediate (A) and 50 g of vinyloxazolidone were dissolved in 150 ml of N-methylpyrrolidone and added with 3.75 g of AZBN. The mixture was heated at 85° C. for 24 hours in a flask provided with stirrer and reflux condenser. The product was cooled, precipitated in ethyl ether (2 liters), washed with ether and dried. It was then redissolved in DMF and re-precipitated in ethyl ether. The yield was 32.7 g of a product soluble in water and dimethylformamide, containing about 37% w/w of aminoallylidenmalononitrile moieties.
