Reaction Steps
To a solution of 1H-pyrrole-2-carboxylic acid (1 g, 9 mmol) (Aldrich, Milwaukee, Wis.) in DCM (15 mL) was added oxalyl chloride (1.1 mL) and DMF (3 drops). The mixture was stirred at room temperature resulting in 1H-pyrrole-2-carbonyl chloride. Methylamine (30 mmol) was then added to the acid chloride and the mixture was stirred at room temperature. The reaction was diluted with ethyl acetate, washed with brine (2×), NaHCO3, dried and concentrated to give 1H-pyrrole-2-carboxylic acid methylamide.
