Participants

Reaction Steps

To a mixture of naphthalene-2,6-dicarboxylic acid (5 g), methylamine hydrochloride (1.64 g) and 1-hydroxybenzotriazole (3.75 g) in dimethylformamide (50 ml) was added 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (3.79 g) under ice-cooling. The mixture was stirred for 1 hour at the same temperature and then at ambient temperature overnight. The mixture was diluted with water, and the precipitates were collected by filtration to give 6-(methylcarbamoyl)naphthalene-2-carboxylic acid (4.07 g).
