The acid hydrolysis of the readily obtainable 3-(o-carboxyphenyl)sydnones (6a-d) afforded 3-indazolones (3a-d) in yields over 90 percent. By transacylation between 1-acyl-3-acyloxyindazoles (11a-d) and 3-indazolones (3a, c), the corresponding 1-acyl-3-indazolones 10a-d resulted in pure state and yields also over 90 percent.
