Title (EN) METHOD FOR PRODUCING BENZOXAZOLE COMPOUND
(FR) PROCÉDÉ DE PRODUCTION DE COMPOSÉ DE BENZOXAZOLE
(JA) ベンゾオキサゾール化合物の製造方法
Abstract:
(EN) A method for producing a compound represented by formula (3) (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. (In formula (3), n represents 1, 2, 3 or 4.) A method for producing the compound represented by formula (3) by a step for producing the compound represented by formula (2) by means of 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.
(JA) 式(2)で示される化合物(以下、化合物(2)と記す)、トリ(C1-C3アルキル)シリル(C1-C4パーフルオロアルカン)及びフッ化物を混合することによる、式(3)[式中、nは、1、2、3、又は4を表す。] で示される化合物(以下、化合物(3)と記す)の製造方法。 式(1)で示される化合物を分子内脱水縮合することにより、前記式(2)で示される化合物を製造する工程、及び前記式(2)で示される化合物、トリ(C1-C3アルキル)シリル(C1-C4パーフルオロアルカン)及びフッ化物を混合することによる、前記式(3)で示される化合物の製造方法。
