Ammonia → Naphthalene-2-carboxamide

Participants

Reaction Steps

A solution of 2-naphthoyl chloride (5.70 g, 29.9 mmol) in tetrahydrofuran (60 ml) was added dropwise to a mixture of 28% aqueous ammonia (20 ml) and tetrahydrofuran (30 ml) with stirring under ice cooling, and the mixture was stirred at room temperature for 4 hrs. The solvent was distilled off under reduced pressure, and water was added to the residue. The precipitates were collected by filtration and dried to give 2-carbamoylnaphthalene (2.68 g, 52%) as a colorless solid.
