Application | 3-pyridinium amidoxime hydrochloride is a pharmaceutical intermediate, it can be prepared from 3-cyanopyridine by one-step reaction with hydroxylamine hydrochloride. It has been reported that it can be used to prepare the compound N-hydroxy-N-((R)-2-((S)-6-(3-(pyridin-3-yl)-1,2, 4-oxadiazol-5-yl)-5-azaspiro [2.4] heptane-5-carbonyl) hexyl) formamide, the compound is a kind of novel structure, the Spiro ternary ring and Spiro 5-membered ring peptide deformylase inhibitors with better activity and less toxicity are used to inhibit bacteria resistant to existing antibiotics. |
preparation | 3-cyanopyridine (5.2g,50mmol) was dissolved in 50ml of ethanol, hydroxylamine hydrochloride (4.2g,60mmol),NaHCO3(5.0g,60mmol) and water (3ml) were then added. The mixture was heated at reflux for 12 hours. Anhydrous Na2SO4 was added, filtered and diluted with diethyl ether (50ml) to give white crystals (6.6g,96% yield). |
