(Problems to be Solved by the Invention) However, in these methods, since the protecting group of the aglycone and that of the sugar are different, two steps are required for their removal. That is, hydrogenolysis is performed using palladium-carbon as a catalyst to remove the benzyloxycarbonyl group, which is the protecting group at the 4' position of the aglycone, and zinc acetate is used to remove the acetyl or formyl group, which is the protecting group of the sugar. ing. % Removal of sugar protecting groups requires high temperature and long time; for example, even if the reaction is allowed to proceed for 20 to 30 hours, the reaction will not be completed, and if the reaction is continued further, by-products will increase, resulting in a decrease in yield and industrial This is not preferred as a commercial manufacturing method.
