摘要
Abstract
Objective To improve the synthesis technology of 2-(2-Hydroxy-4'-aminophenyl) benzothiazole.Methods With oamino-thiophenol and aminosalicylate as the raw materials,the synthesis method was improved through etherification and Vilsmeier reaction.Results The reaction yield rate was increased from 50% to 81.7%,the reaction temperature was decreased from 150 ℃ to mild 50 ℃,and the reaction time was shortened from 3 h to 45 min.Conclusion The improved technology not only reduces the cost,but also increases the environmental friendliness of the reaction.关键词
