2-Acetylbenzoic acid azide was prepared by reacting 2-acetoxybenzoyl chloride with sodium azide in acetone and water at 0-5° C. for 24 hours. It had an IR peak at 2245 cm−1 (azide). The crude azide was then heated in benzene at 70-75° C. under nitrogen for 2 hours to give 2-acetoxyphenylisocyanate.
