A process of producing a compound of formula (3), wherein R1 is a C1-5alkyl group, R2 is a halogen atom, a C1-5 alkyl group, a C2-5 alkenyl group, a C2-5 alkynyl group, a C1-5 alkyl group, a C1-5 alkoxy group, a nitro group, or a hydroxy group, wherein multiple R2 may be the same or may be different, and a is an integer of from 0 to 4, comprising reacting a compound of formula (2), wherein R2 and a are as defined above with a C1-5-alkanesulfonyl chloride or C1-5-alkanesulfonic acid anhydride followed by hydrolyzing an N,N-disulfonated derivative of compound (3) to the compound of formula (3).

L'invention concerne un procédé destiné à produire un composé de formule (3), dans laquelle R1 est un groupe alkyle C1-5, R2 est un atome d'halogène, un groupe alkyle C1-5, un groupe alcényle C2-5, un groupe alkynyle C2-5, un groupe alcoxy C1-5, un groupe nitro ou un groupe hydroxy, de multiples R2 pouvant être identiques ou différents, et a est un nombre entier compris entre 0 et 4. Ce procédé consiste à faire réagir un composé de formule (2), dans laquelle R2 et a sont tels que définis ci-dessus, avec un chlorure de C1-5-alcanesulfonyle ou un anhydride d'acide C1-5-alcanesulfonique, puis à hydrolyser un dérivé N,N-disulfoné du composé (3) en composé de formule (3).
