Reaction Steps

45 parts of acrylamidoglycolic acid, 90 parts trimethylorthoformate, 0.045 parts of the mono methyl ether of hydroquinone and 35 parts of methanol are mixed in a flask equipped with a stirrer, condensor and thermometer. The mixture was heated at a bath temperature of 60°-65° C. for 24 hours. A small amount of insoluble material was filtered off and discarded. The filtrate was stripped of solvent under vacuum and a rubbery substance was obtained. This material was extracted with ether with stirring for 3 days. The solid which was insoluble in the ether was filtered off and was further extracted with acetone. The acetone was removed to yield 24 g of crude AGME (Mp. 100-102.5).
