Synthetic Route of 104-38-1, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.104-38-1, name is 1,4-Bis(2-hydroxyethoxy)benzene, molecular formula is C10H14O4, molecular weight is 198.2158, as common compound, the synthetic route is as follows.
General procedure: Chromonecarbonyl chloride was prepared by the reaction ofacid with thionyl chloride. After a toluene solution of 2-chromoniccarboxylic acid (1.4 g, 7.6 mmol) and thionyl chloride (1.1 g,9.1 mmol) was stirred at 90C for 2e3 h, thionyl chloride wasremoved under reduced pressure. The toluene solution of the cor-responding polyethers 4a-4c (0.5 g, 2.5 mmol) and chromone-carbonyl chloride was stirred at 120C overnight. After baseextraction, the solvent was removed under reduced pressure, andthe residue was separated by silica gel column chromatography(hexane/ethyl acetate) to obtain the corresponding chromone de-rivatives 5a-i in 30e92% yields.
Statistics shows that 104-38-1 is playing an increasingly important role. we look forward to future research findings about 1,4-Bis(2-hydroxyethoxy)benzene.
