실험 절차

A mixture of 65.6 g of 1-methoxymethyl-2-pyrrolidone, 75.5 g of acrylarnide, 0.20 g of p-toluene sulfonic acid and 0.20 g of phenothiazine was stirred under N2 atmosphere at 150° C. for 1 hour, during which time the methanol was removed by distillation. The residue was cooled, and recrystallized from acetone to give the title compound in a yield of 40%. mp: 73-74° C.
