Abstract
Procedure for preparing benzofuranone derivatives of formula I **(See formula)** wherein R1 is alkyl of 1 to 10 carbon atoms, cycloalkyl of 3 to 8 carbon atoms or phenyl, and R2 is hydrogen or alkyl of 1 to 4 carbon atoms, with the proviso that when it is hydrogen, R1 does not mean methyl; characterized in that a compound of formula II is lactonized **(See formula)** where R1 and R2 have the meanings indicated above.
