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.

used cardiovascular drug. The traditional batch synthesis process suffers from long reaction times, tedious operations, and unstable yields. Herein, a sequential continuousflowsynthesis combined with a multistage in-line purification process of calcium dibutyryladenosine cyclophosphate was developed. The acylation reaction was completed in a continuous coil reactor at 160 °C in 20 min. And the high
