Title
(EN) METHOD FOR PRODUCING BENZOXAZOLE COMPOUND
(ZH) 用于制备苯并噁唑化合物的方法
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)"), atri(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.

(ZH)
