In 2008,Synthetic Communications included an article by Dai, Liyan; Fan, Dongbo; Wang, Xiaozhong; Chen, Yingqi. Product Details of 153476-68-7. The article was titled 《Improved synthetic approach to tenatoprazole》. The information in the text is summarized as follows:

An improved synthetic approach to tenatoprazole I was described. It started from 2,3,5-trimethyl-4-nitropyridine-N-oxide with acetic anhydride via rearrangement and hydrolysis to give 2-hydroxymethyl-3,5-dimethyl-4-nitropyridine, chlorination with SOCl2 yielded 2-chloromethyl-3,5-dimethyl-4-nitropyridine hydrochloride (II), then II condensed with 2-mercapto-5-methoxyimidazole[4,5-b]pyridine to give 5-methoxy-2-[(4-nitro-3,5-dimethyl-2-pyridinyl)methylthio]imidazole[4,5-b]pyridine (III). At last the title compound I was produced by two methods: the compound III was oxidized with MCPBA and then methoxylated with CH3ONa to give I and III was first methoxylated with CH3ONa and then oxidized with MCPBA to give I. The overall yield was around 26% for both five-step syntheses. In the part of experimental materials, we found many familiar compounds, such as 2-(Chloromethyl)-3,5-dimethyl-4-nitropyridine(cas: 153476-68-7Product Details of 153476-68-7)

2-(Chloromethyl)-3,5-dimethyl-4-nitropyridine(cas: 153476-68-7) belongs to pyridine. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. As ligands, solvents, and catalysts they facilitate reactions; thus descriptions of these new ligands and their applications abound each year.Product Details of 153476-68-7

《H3PW12O40: an efficient and green catalyst for the facile and selective oxidation of sulfides to sulfoxides, applied to the last step of the synthesis of omeprazole》 was published in Iranian Journal of Chemistry & Chemical Engineering in 2017. These research results belong to Esfandyari, Maryam; Heravi, Majid; Oskooie, Hossein; Fotouhi, Lida; Tajbakhsh, Mahmood; Bamoharram, Fatemeh. Name: 2-(Chloromethyl)-3,5-dimethyl-4-nitropyridine The article mentions the following:

Omeprazole, (6-methoxy-2-((4-methoxy-3,5-dimethylpyridin-2-yl)methylsulfinyl)-1H-benzimidazole) is a well-established prescribed drug, exhibits proton pump inhibitor activity. In this work, a novel, facile, economical and selective oxidation approach using H3PW12O40 as Keggin type heteropolyacids along with H2O2 in the last step of the conventional synthesis of this compound as well as its derivatives under environmental-benign conditions, is reported. This protocol can be well adopted for pilot plant scale giving a high pure pharmacopeia grade material. Our synthetic route involves the use of various heteropolyacids as heterogeneous catalysts. Due to the obtained results, it was concluded that Keggin type heteropolyacid , is an effective catalyst for this purpose. The optimized condition for the last step of this synthesis was applied to the synthesis of lansoprazole, pantoprazole, and rabeprazole. The experimental part of the paper was very detailed, including the reaction process of 2-(Chloromethyl)-3,5-dimethyl-4-nitropyridine(cas: 153476-68-7Name: 2-(Chloromethyl)-3,5-dimethyl-4-nitropyridine)

2-(Chloromethyl)-3,5-dimethyl-4-nitropyridine(cas: 153476-68-7) belongs to pyridine. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Additionally, pyridine-based natural products continue to be discovered and studied for their properties and to understand their biosynthesis.Name: 2-(Chloromethyl)-3,5-dimethyl-4-nitropyridine
