PROCESSO PARA A PREPARACAO DE NOVAS ACETAMIDAS DERIVADAS DA 2,3-DIHIDRO-3-FENIL-2-BENZOFURANONA

The invention relates to new acetamides derived from 2,3-dihydro-3-phenyl-2-benzofuranone, of general formula I (I) in which: R1 denotes a hydrogen or halogen atom, R2 and R3, which may be identical or different, each denote a hydrogen atom or a linear or branched alkyl radical containing 1 to 4 carbon atoms, a benzyl radical optionally substituted with a halogen atom, with an alkoxy radical containing 1 to 4 carbon atoms or with an alkyl radical having 1 to 4 carbon atoms, or a 3,4-methylenedioxybenzyl radical, or form, together with the nitrogen to which they are attached, a 4-morpholinyl radical or a 1-piperazinyl radical.
