Phosgene → 4-(2-Naphthyloxy)phenyl isocyanate

Participants

Reaction Steps

A solution of 4-(2-naphthyloxy)aniline (4 g) in toluene (100 ml) was dropwise added to a solution of phosgene (3.5 g) in toluene (50 ml), and the resulting mixture was refluxed for 1 hour. After removal of the solvent from the reaction mixture by distillation under reduced pressure, the residue was distilled in vacuo to give 4-(2-naphthyloxy)phenyl isocyanate (4.1 g) as a fraction boiling at 137° to 149° C./0.8 mmHg. M.P., 75°-77° C.
