Reaction Steps

Methyl 3-methyl-1H-pyrrole-2-carboxylate (10 g, 0.07 mol, purchased at Aurora Building Blocks, reference number A00.567.027) was dissolved in 200 mL methanol and a solution of sodium hydroxide (2N, 108 mL, 0.22 mol) was added. The mixture was heated at 60° C. overnight. The solvent was evaporated and the residue was acidified to pH 2-3 with 2N hydrochloric acid. A white precipitate was formed and filtered and washed with cool water. The solid was dried in a vacuum oven to give 6.97 g (77% yield) of the desired compound. Purity 100%.
