The article was titled 《Synthesis and characterization of N-(4-(piperidin-4-ylsulfonyl)phenyl)5-vinylpyrimidin-2-amine》, and you may find the article in Indian Journal of Heterocyclic Chemistry.Reference of tert-Butyl 4-hydroxypiperidine-1-carboxylate The information in the text is summarized as follows:
Target product N-(4-(piperidin-4-ylsulfonyl)phenyl)5-vinylpyrimidin-2- amine was synthesized using 6-oxopyran-3-carbaldehyde and 4-hydroxypiperidine as starting materials by a series of nucleophilic substitution and oxidation Different acid-binding agents were discussed to explore the effect on the yield of tert-Bu 4-((4-((5-vinylpyrimidin-2-yl)amino)phenyl)sulfonyl)piperidine-1- carboxylate. The structures of products were characterized by 1H NMR and mass spectra. In the part of experimental materials, we found many familiar compounds, such as tert-Butyl 4-hydroxypiperidine-1-carboxylate(cas: 109384-19-2Reference of tert-Butyl 4-hydroxypiperidine-1-carboxylate)
tert-Butyl 4-hydroxypiperidine-1-carboxylate(cas:109384-19-2) is a 4-hydroxypyridine with a boc protecting group used in the preparation of neurologically active agents and other pharmaceutical compounds.Reference of tert-Butyl 4-hydroxypiperidine-1-carboxylate
