Procedure
A mixture of 140 g of N-carbamylmaleimide (1 mole), 121.8 g of 2-hydroxyethyl acrylate (1.05 moles) and 1.36 g of zinc chloride (0.01 moles) in 200 mL of acetonitrile was heated to reflux. After 5 hours, the mixture was poured into 500 mL of water. The solid was filtered, washed with water and dried to afford 240.7 g (94% yield) of 2-hydroxyethyl acrylate maleurate. M.P.: 88°-90° C. (dec.); 1H NMR (CDCl3): δ10.4 (br s, 1H), 8.2 (br s, 1H), 6.4 (m, 3H), 6.2 (d of d, 1H), 5.9 (m, 2H), 4.4 (A2B2, 4H); 13C NMR (CDCl3): δ165.9, 165.3, 165.2, 155.1, 133.1, 131.6, 129.5, 127.8, 63.2, 61.9; HPLC (10% CH3CN/H2O, C18): Rt=5.7 minutes.
