    摘要: The object of the present invention is to provide a method for preparing 4-(piperidin-4-yl)morpholine, which is easy to operate. The object can be solved by a method for preparing 4-(1-benzylpiperidin-4-yl)morpholine, characterized in that 5-fold molar or more of morpholine is added to 1-benzyl-4-piperidone, and the mixture is reacted with hydrogen under 1 MPa or less in the presence of platinum catalyst or palladium catalyst.

    摘要: A glyoxal-guanosine-group compound is prepared either by reacting glyoxal-guanine with any one of ribose-1-phosphate and 2-deoxyribose-1-phosphate in the presence of purine nucleoside phosphorylase, or by reacting glyoxal-guanine with any one selected from the group consisting of uridine, 2'-deoxyuridine and thymidine, together with phosphate ion, in the presence of purine nucleoside phosphorylase and pyrimidine nucleoside phosphorylase. The glyoxal-guanosine-group compound is then decomposed by alkali, whereby a guanosine-group compound consisting of guanosine and 2'-deoxyguanosine is prepared.
