Title: (DE) VERFAHREN ZUR HERSTELLUNG EINER BENZOXAZOLVERBINDUNG
(EN) METHOD FOR PRODUCING BENZOXAZOLE COMPOUND
(FR) PROCÉDÉ DE PRODUCTION DE COMPOSÉ DE BENZOXAZOLE
Abstract:
(EN) A method for producing a compound represented by formula (3) (wherein n is 1, 2, 3 or 4.) (hereinafter referred to as "compound (3)") by mixing a compound represented by formula (2) (hereinafter referred to as "compound (2)"), a tri(C1-C3 alkyl)silyl(C1-C4 perfluoroalkane) and a fluoride. A method for producing the compound represented by formula (3) by a step for producing the compound represented by formula (2) by an intramolecular dehydration condensation of a compound represented by formula (1) and by a step for mixing the compound represented by formula (2), a tri(C1-C3 alkyl)silyl(C1-C4 perfluoroalkane) and a fluoride.
(FR) La présente invention concerne un procédé de production d'un composé représenté par la formule (3) (appelé ci-après "composé (3)") par mélange d'un composé représenté par la formule (2) (appelé ci-après "composé (2)"), d’un tri(alkyle en C1-C3)silyl(perfluoroalcane en C1-C4) et d’un fluorure. (Dans la formule (3), n représente 1, 2, 3 ou 4.) L’invention concerne un procédé de production du composé représenté par la formule (3) par une étape de production du composé représenté par la formule (2) au moyen d’une condensation par déshydratation intramoléculaire d'un composé représenté par la formule (1) et par une étape de mélange du composé représenté par la formule (2) et, d’un tri(alkyle en C1-C3)silyl(perfluoroalcane en C1-C4) et d’un fluorure.
