Title:
METHOD FOR PRODUCING BENZOXAZOLE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2017/138237
Kind Code:
A1
Abstract:
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.
