Preparation method of purine nucleotide intermediate

The invention relates to the technical field of medical intermediates, particularly to a preparation method of a purine nucleotide intermediate. The synthesis route of the preparation method comprises steps as follows: 1) carrying out a chlorination reaction on a raw material compound V and a thionyl chloride/hydrogen peroxide reaction system to obtain a compound IV; 2) reacting the compound IV with methylamine to obtain a compound III; and 3) reacting the compound III with a compound II in the presence of a catalyst to obtain a compound I. According to the invention, the synthetic route of the purine nucleotide intermediate is improved, the methylation is firstly carried out, and then the deprotection is carried out, so that the reaction condition is mild, the operation is simple, the yield and the purity are higher, and the method is suitable for industrial large-scale production.
