Reaction Steps
A 5.48 ml (0.042 mol) sample of diethyl sulfate was added to a suspension of 6.12 g (0.040) of 1,4-dimethylpyrrole-2-acetic acid and 16.6 g (0.12 mol) of potassium carbonate in 50 ml of DMSO. The mixture was stirred for 6 hours at room temperature. It was poured into water and extracted with ether. The ether extract was washed with brine, dried (MgSO4) and the solvent was evaporated in vacuo. The oily residue was distilled to give 6.0 g of ethyl 1,4-dimethylpyrrole-2-acetate, bp 68° at 0.005 Torr as a colorless oil.
