Reaction Steps

A solution of 2.5 g. of sodium methoxide in 25 ml. of methanol is cooled to 10° C. and a mixture of 7.0 g. of ethyl 4-nitro-2-pyrrolecarboxylate in 15 ml. of methanol is added. After 10 minutes, 18.6 g. of methyl iodide is added. The dark-colored solution is warmed to 35° C. for 0.5 hours, then cooled and allowed to stir at room temperature for 16 hours. Chilling and filtration affords a solid which is collected by filtration and recrystallized from ethanol to yield the product.
