Paragraph 0574-0577, (2016/12/26)
There is provided a production method of a compound represented by the following formula (II) through a step of reacting a compound represented by the following General Formula (I) with a sulfur compound. In General Formulas (I) and (II), R1 represents a hydrogen atom or an acyl group, R2 represents a hydrogen atom, a fluorine atom, an acyloxy group, an arylmethyloxy group, an allyloxy group, an arylmethyloxycarbonyloxy group, or an allyloxycarbonyloxy group, R3 represents a hydrogen atom or an acyloxy group, R5 represents an alkyl group or an aryl group, and X represents a leaving group. Here, in a case where R2 is a fluorine atom, an acyloxy group, an arylmethyloxy group, an allyloxy group, an arylmethyloxycarbonyloxy group, or an allyloxycarbonyloxy group, R3 is an acyloxy group.
