SYNTHESIS AND METHOD OF PURIFICATION OF CYCLIC NUCLEOTIDE DERIVATIVES

摘要

The present invention relates to methods for the synthesis and purification of cyclic nucleotide derivatives. The present invention provides a method for separating a cyclic nucleotide derivative from a mixture resulting from a chemical reaction to produce a cyclic nucleotide derivative from a cyclic nucleotide. In one embodiment, this mixture may comprise a cyclic nucleotide derivative, a pyridine solvent, and at least one of an alkyl carboxylic acid, an alkyl acid halide, or an alkyl carboxylic acid anhydride. In another embodiment, this mixture may comprise a cyclic nucleotide derivative and at least one of an alkyl carboxylic acid, an alkyl acid halide, or an alkyl carboxylic acid anhydride.
