β-(2,4,6-Trimethylbenzoyl)-acryloyl chloride reacts with anthranilic acid to give (I) which is easily cyclized by the action of acetic anhydride to give the benzoxazone (II). Condensation of (II) with hydrazine hydrate gave (III). The behaviour of (III) towards the action of aromatic aldehydes, ketones, phthalic anhydride and phthalyl amino acid chlorides has been investigated. Reactions of (II) with o-phenylene diamine, ammonia, Grignard reagents, Friedl-Crafts reaction and bromine has been described.
