PROCESS FOR PRODUCING NUCLEOSIDE

There is a demand for a convenient production method of an NC type purine nucleoside. The present invention relates to a method of producing a purine nucleoside represented the formula (I') or a salt thereof, which comprising reacting a pyrimidine nucleoside represented by the formula (I) or a salt thereof with a purine nucleobase represented by the formula B'H in the presence of a Lewis acid.
