Method for producing glycoside compound

Abstract

A purpose of the present invention is to provide a method for producing a glycoside compound having a high purity. The present invention provides a method for producing a glycoside compound represented by formula (3) (wherein Ba, i-Pr and n are the same as those defined below), which comprises reacting a glycoside compound of formula (1) (wherein Ba represents an adenine group which may be optionally substituted with an acyl group, and i-Pr represents an isopropyl group) with an ether compound of formula (2) (wherein R1 represents a C1-C6 alkyl group or a phenyl group, and n is 0 or 1) in one or more solvents selected from tetrahydropyran and 4-methyltetrahydropyran in the presence of one or more halogenated agents selected from halogen, N-halogenated succinimide, and N-halogenated hydantoin.
