Mono-N,N-dimethyl-4-aminopyridinium sn-glycerol-3-phosphate, production and use thereof in preparation of phosphatidic acids.

摘要

A process for preparing crystalline N,N-dialkyl-4-aminopyridinium salts from sn-glycerol-3-phosphate or an analogue thereof characterised in that it comprises: (a) reacting a free acid form of sn-glycerol-3-phosphate or an analogue thereof with an N,N-dialkyl-4-aminopyridine to form a salt solution; and (b) obtaining the N,N-dialkyl-4-aminopyridinium sn-glycerol-3-phosphate salt from the salt solution by precipitation with an organic solvent one or more times is disclosed. A process for the preparation of a phosphatidic acid is also disclosed.
