The reaction was cooled to 0° C. with an ice bath and neutralized to pH 0 with 1.7 l HCl (conc.) while maintaining the temperature below 10° C. A black precipitate was removed by filtration through Celite and the product was extracted with 20 liters of ethyl acetate. The organic layer was dried with sodium sulfate and concentrated-in vacuo to provide 4-nitropyrrole-2-carboxylic acid (140 g, 0.9 mol) as a brown solid which was used without further purification. To a solution of 4-nitropyrrole-2-carboxylic acid (140 g, 0.9 mol) dissolved in 180 ml of methanol was added 8 ml of concentrated sulfuric acid. The solution was refluxed for 15 hours, cooled to 0° C. and 90 ml of water was added. The solution was then allowed to stand at −20° C. for 2 days. The resulting light brown crystals were collected by vacuum filtration to yield pure methyl 4-nitropyrrole-2-carboxylate (49) (105 g, 0.62 mol) in 23% overall yield. 1H NMR (DMSO-d6) δ14.2 (br s, 1H), 7.74 (d. 1H, J=1.6 Hz), 7.35 (d, 1H, J=1.7 Hz), 3.73 (s, 3H).
