Reaction Steps
A solution of 12.41 g of N-methoxycarbonyl-3-carboethoxyacetyl-4-pyrrolidino-2,5-dihydropyrrole, 9.64 ml of N,N-dimethylformamide dimethylacetal and 10 mg of urea in 50 ml of dioxane is stirred under nitrogen for 16 hours. Evaporation of the solvent yields N-methoxycarbonyl-3-(2-ethoxycarbonyl-3-dimethylaminoacryloyl)-4-pyrrolidino-2,5-dihydropyrrole as an oil.
