To a three-necked flask equipped with a stirrer and an extractor filled with a molecular sieve drying agent was added 300 parts acrylamidoglycolic acid, 3000 parts methanol, 0.05 parts phenothiazine, 4.5 parts 98% sulfuric acid and 200 parts chloroform. The mixture was heated to reflux and the distillate was allowed to pass through the extractor for 61/2 hours. The mixture was cooled and allowed to stand for 16 hours at which point the mixture was warmed to about 40° C., 19 g of sodium carbonate was added, and the solution was stirred for 21/2 hours. The mixture was filtered and vacuum stripped of solvent. The solid residue was extracted with chloroform. Diethyl ether was added to the extract and a polymeric mass precipitated which was discarded. The remaining extract was stripped of solvent to yield 264.2 parts of crude MAGME which was confirmed by chemical analysis.
