Methanol → Methyl pyrrole-2-carboxylate

Participants

Reaction Steps

40 ml of a solution of 45 (mmoles) of 2-chlorocarbonyl-1H-pyrrole in methylene chloride were added dropwise to a cold mixture of 4.3 ml of pyridine and 3.5 ml of methanol and the mixture was washed with water, then with 6 ml of N sodium hydroxide, and was extracted with methylene chloride. The organic phases were dried and concentrated to dryness and the residue was chromatographed over silica. Elution with a mixture of hexane and ethyl acetate (8-2) yielded 4.014 g of methyl 1H-pyrrole-2-carboxylate melting at ≃74° C.
