Dimethylformamide → Methyl 3-(2-carbamoylpyrrol-1-yl)benzoate

Participants

Reaction Steps

28% Ammonia aqueous solution (0.4 ml) was added to a mixture of methyl 3-(2-trichloroacetylpyrrol-1-yl)benzoate (1.0 g) and N,N-dimethylformamide (2 ml), and the mixture was stirred for 1.5 hours at ambient temperature. The mixture was poured into a mixture of ethyl acetate and water. The separated organic layer was washed with water, dried over magnesium sulfate and evaporated in vacuo. The residue was triturated with diisopropyl ether to give methyl 3-(2-carbamoylpyrrol-1-yl)benzoate (0.61 g).
