Methyl iodide → Methyl 3-(2-trimethylammoniomethylpyrrol-1-yl)benzoate iodide

Participants

Reaction Steps

Methyl iodide (4.8 ml) was added dropwise to the mixture of methyl 3-(2-dimethylaminomethylpyrrol-1-yl)benzoate (10.0 g) and ethyl acetate (50 ml) at ambient temperature, and the mixture was stirred for 2 hours at the same temperature. The isolated precipitate was collected by filtration and dried to give methyl 3-(2-trimethylammoniomethylpyrrol-1-yl)benzoate iodide (13.52 g).
