Procedure
25 g of intermediate (A) and 25 g of vinylpyrrolidone were dissolved in 100 ml of N-methylpyrrolidone and added with 2.5 g of AZBN. The mixture was then heated to reflux at 85° C. for 6 hours in a flask provided with a stirrer and reflux condenser, then it was cooled, precipitated in ether and dried at 50° C. The yield was 15.7 g of a product soluble in 40:60 water-ethanol, containing about 44% w/w of aminoallylidenmalononitrile moieties.
