Application

2-(Chloromethyl)-3,4-dimethoxypyridine hydrochloride may be used as a precursor for the preparation [(2-pyridyl)-2-ethyl]-[3,4-dimethoxy-(2-pyridylmethyl)]-N-methylamine.

General description

2-(Chloromethyl)-3,4-dimethoxypyridine hydrochloride (CDP) can be synthesized using maltol as a starting material. CDP and DMS (dimethyl sulfate) are used in the preparation of pantoprazole sodium (PPS), an antiulcerative drug. The quantification of CDP and DMS in PPS can be done simultaneously by gas chromatography–mass spectrometry (GC-MS) method.
