Disclosed therein is a method for preparing the 3'-amino-2',3'-dideoxyguanosine, comprising the steps of: (a) treating 3'-amino-3'-deoxythymidine and 2,6-diaminopurine with a pyrimidine nucleoside phosphorylase and a purine nucleoside phosphorylase to prepare 3'-amino-2',3'-dideoxyribosyl 2,6-diaminopurine; and (b) converting enzymatically the 3'-amino-2',3'-dideoxyribosyl 2,6-diaminopurine with an adenosine deaminase to prepare 3'-amino-2',3'-dideoxyguanosine. According to the present invention, 3'-amino-2',3'-dideoxyguanosine may be obtained with very high yield in a relatively simple procedure.
