Application of 17282-40-5, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 17282-40-5, name is 1-(2-Ethoxy-2-oxoethyl)pyridin-1-ium bromide. This compound has unique chemical properties. The synthetic route is as follows.
General procedure: Mixture of ethyl acetoacetate(1, 211 mg, 0.153 mmol), hydrazine (2, 81 mg, 0.153), 7-hydroxy-4-oxo-2-phenyl-4H-chromene-8-carbaldehyde (4a, 406 mg,0.153 mmol), 1-(2-ethoxy-2-oxoethyl)pyridinium ylide (4, 272mg, 0.153 mmol), 0.1 equivalents of trimethylamine (16 mg,0.015 mmol) in15 mL EtOH were refluxed in a pre-heated oilbath (80 C) under the blanket of nitrogen for 30 min till the completion of reaction (TLC, 20 % dicholromethane in hexanes; Rf = 0.3). The reaction mixture was diluted with dichloromethane (10 mL) and the organic solution was washed with water (20 mL) and brine (20 mL) and dried over anhydrousNa2SO4. Column chromatographic purification on silica gelwith increasing amount of dichlormethane in hexanes provided 8a as a free flowing solid in about 88 % yield. Analytical samples were obtained through from the recrystallization in EtOH.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 17282-40-5, 1-(2-Ethoxy-2-oxoethyl)pyridin-1-ium bromide.
