N-Bromosuccinimide/Dibromodimethylhydantoin in aqueous base: A practical method for the bromination of activated benzoic acids
摘要:
A new bromination method employing NBS or dibromodimethylhydantoin in aqueous base is described for the synthesis of 3-bromo-2,6-dimethoxybenzoic acid (1) and other monobrominated alkoxybenzoic acids.
(EN) A novel procedure for bromination of aromatic moieties utilizes N-bromosuccinimide or dibromodimethylhydantoin in an aqueous alkali medium. The bromination procedure is employed for the preparation of an intermediate used in the preparation of remoxipride, an antipsychotic compound.(FR) Nouveau procédé de bromination de fractions aromatiques faisant appel à du N-bromosuccinimide ou à de la dibromodiméthylhydantoïne dans un milieu alcalin aqueux. Ledit procédé de bromination est utilisé pour préparer un intermédiaire qui entre dans la composition du remoxipride, un composé antipsychotique.
