Abstract A simple and efficient protocol for the one-pot synthesis of 1-amidoalkyl-2-naphthols and novel 1-carbamatoalkyl-2-naphthols has been described undersolvent-freeconditions, using N-methyl-2-pyrrolidone hydrogen sulfate as a reusable Brønsted acidic ionic liquid. This methodology has several advantages such as use of a halogen-free ionic liquid , excellent yields, short reaction time, easy
