Chemoselective Demethylation of Methoxypyridine

A chemoselective demethylation method for various methoxypyridine derivatives has been developed. Treatment of 4-methoxypyridine with L-selectride in THF for 2 h at reflux temperature afforded 4-hydroxypyridine in good yield; no reaction to anisole occurred. The utility of our method was demonstrated by the efficient synthesis of the metabolic substances of the antiulcer agent omeprazole. Chemoselective demethylation at the site of 3,5-dimethyl-4-methoxypyridine in the presence of 4-methoxybenzimidazole was achieved.

Site selective syntheses of [3H]omeprazole using hydrogen isotope exchange chemistry

Omeprazole (Prilosec) is a selective and irreversible proton pump inhibitor used to treat various medical conditions related to the production of excess stomach acids. It functions by suppressing secretion of those acids. Radiolabeled compounds are commonly employed in the drug discovery and development process to support efforts including library screening, target identification, receptor binding, assay development and validation and safety assessment. Herein, we describe synthetic approaches to the controlled and selective labeling of omeprazole with tritium via hydrogen isotope exchange chemistry. The chemistry may also be used to prepare tritium labeled esomeprazole (Nexium), the active pure (S)-enantiomer of omeprazole.

Process for preparing 2-(2-pyridylmethyl)-sulfinyl-1H-benzimidazoles and the intermediate compounds used therein

The present invention relates to a process for preparing 2-(2-pyridylmethyl)sulphinyl-1H-benzimidazoles that are proton pump inhibitors, using as intermediates 2-benzimidazolylsulphinic acid derivatives. The present invention also relates to said intermediate compounds, their use and a process for the preparation thereof. These novel intermediate compounds are 2-benzimidazolylsulphinic acid esters that are obtained from their corresponding alkaline salts, which are in turn obtained by oxidation of substituted 2-mercaptobenzimidazoles. The intermediate compounds of the invention are converted into 2-(2-pyridylmethyl)sulphinyl-1H-benzimidazoles by reaction with substituted 2-methylpyridines.

With the aid of DCx and DPP Omeprazol (1) can be determined in Britton-Robinson-buffers (BRP, pH 7-9) up to a concentration of 10~5 M. The mechanism of the reduction process on the DME could be elucidated. With consumption of two electrons and two protons 1 will be reduced to 5-methoxy-2-[(3,5-dimethyl-4-methoxypyridin-2-yl)methylthio]-l Hbenzimidazole which will be cleaved with uptake of two further electrons and two protons into 4-methoxy-2,3,5-trimethylpyridine and 2-mercapto-5-methoxybenzimidazole.

Synthesis of 4-methoxy-2,3,5-trimethylpyridine: a specific building block for compounds with gastric-acid inhibiting activity.

A new synthesis of 4-methoxy-2,3,5-trimethylpyridine (2), an important building block for the preparation of gastric-acid inhibiting compounds, is described. Condensation of ethyl 3-amino-2-methyl-2-butenoate (3) and diethyl 2-methylmalonate (4) gives 4-hydroxy-3,5,6-trimethyl-2(1H)-pyridone 5. Reaction of 5 with phosphoryl chloride affords 2,4-dichloro-3,5,6-trimethylpyridine (9a), which, upon hydrogenolysis with palladium on charcoal, gives 2,3,5-trimethylpyridine (10). However, selective hydrogenolysis in acidic solution yields 4-chloro-2-3-5-trimethylpyridine (11). Substitution of the chlorine in 11 with methoxide ion gives 4-methoxy-2,3,5-trimethylpyridine (2), which can be oxidized to the corresponding N-oxide (13). This constitutes a new and efficient route to compound 2 in an overall yield of 43%.
