Depending on the solvent used, the alkaline hydrolysis of 2-(2-benzofuranyl)-benzonitriles leads to the expected amide or acid, or to isoindolinones by rearrangement.

Some procedures for a benzofuroisoquinolinone 1 were studied. Its O-analogous benzofuroisocoumarin 2 was synthesized from methyl salicylate with diethyl α-bromohomophthalate (9). And, the benzofuroisoquinolinone 1 was obtained by treating 2 with ammonia gas in a sealed tube.
