Identification and synthesis of potential impurities of rabeprazole sodium

Rabeprazole sodium (1, Achiphex) is a gastric proton pump inhibitor. It causes dose-dependent inhibition of acid secretion and is useful as an anti-ulcer agent. In the process for the preparation of 1, two potential unknown impurities were identified in HPLC at levels ranging from 0.05-0.8%. Based on mass spectral data vide LC-MS, the two impurities were characterized as 2-{[(4-chloro-3-methyl-2-pyridinyl) methyl] sulfinyl}-1H-bezimidazole (2, chloro analogue of rabeprazole) and 2-[{(4-methoxy-3-methyl-2-pyridinyl)methyl} sulfinyl]-1H-benzimidazole (3, methoxy analogue of rabeprazole). The structures were unambiguously established by independently synthesizing them and co-injecting in HPLC. To our knowledge, the compounds 2 and 3 have not been reported as process impurities elsewhere.

Potential antitumor agents. 14. 4 Substituted 2 formylpyridine thiosemicarbazones

A series of 4 substituted 2 formylpyridine thiosemicarbazones has been synthesized which contain a tertiary N at the 4 position. These materials were obtained by reacting 4 nitro 2 picoline N oxide, either directly or after conversion to the corresponding 4 chloro derivative, with a variety of secondary amines. Rearrangement of the 4 substituted 2 picoline N oxides with Ac2O yielded respective methyl acetates, which upon acid hydrolysis, MnO2 oxidation, and reaction with thiosemicarbazide resulted in the desired compounds. An alternate procedure which consisted of reacting 4 chloro 2 formylpyridine ethylene acetal with various amines, followed by hydrolysis and reaction with thiosemicarbazide, was also employed. Introduction of an alkyl group at the 3 position of the pyridine ring of 4 morpholino 2 formylpyridine thiosemicarbazone was achieved by utilizing 2,3 dimethyl 4 nitropyridine N oxide; this material was converted to the corresponding 4 chloro derivative which was then subjected to nucleophilic substitution. 4 Morpholino 2 formylpyridine thiosemicarbazone was the most active antineoplastic agent of this series in mice bearing Sarcoma 180 ascites cells and was significantly superior to 5 hydroxy 2 formylpyridine thiosemicarbazone in this test system.
