The reaction of these in the presence of sodium hydroxide and copper gives N-(2,6-dichlorophenyl)anthranylic acid (3.2.38), the carboxylic group of which undergoes reduction by lithium aluminum hydride. The resulting 2-[(2,6-dicholorphenyl)-amino]-benzyl alcohol (3.2.39) undergoes fu...
2-(3-Carboxy-1-methylindole)acetic acid anhydride (1) reacts with aryldiazonium salts to give 85–95% of the corresponding α-hydrazono anhydrides 2. Treating 2 with boiling hydrazine hydrate in xylene, the respective 2-aryl-4-carbohydrazido-5-methyl-1-oxo-1,2-dihydro-5H/-pyridazino[4...
Acetic anhydride, in the presence of pyridine, reacts quantitatively with anhydrous oxalic acid to form acetic acid, carbon dioxide, and carbon monoxide. Based on this reaction, two small-scale procedures have been devised for the determination of this anhydride. The first, in adaptation of Rosenb...
