To prepare 6-ethoxy-1,3-benzothiazole-2 (3H) -thione, there are many methods, each with its own ingenuity.
First, o-aminothiophenol and ethoxy thiocarbonyl isothiocyanate can be used as starting materials. First, the o-aminothiophenol and ethoxy thiocarbonyl isothiocyanate react slowly in a suitable solvent, such as dichloromethane or toluene, at a mild temperature, about 20 to 30 degrees Celsius, and with the help of acid binding agents such as triethylamine. In this process, the amino group is cleverly combined with the isothiocyanate group, and the thiophenyl group also finds its home, and gradually builds the target molecular framework. After the reaction is completed, the pure product can be obtained by extraction, column chromatography and other methods.
Second, start with 2-amino-4-ethoxybenzoic acid and phosphorus pentasulfide. Place 2-amino-4-ethoxybenzoic acid and phosphorus pentasulfide in a certain ratio in a reactor, use pyridine or quinoline as a solvent, and heat up to 120 to 150 degrees Celsius to fully react. In this reaction, phosphorus pentasulfide exhibits its vulcanization ability, the structure of benzoic acid also undergoes transformation, and the carboxyl group and amino group are synergistically changed to form 6-ethoxy-1,3-benzothiazole-2 (3H) -thione. After the reaction, the satisfactory product can be harvested after cumbersome steps such as cooling, dilution with water, filtration, and recrystallization.
Third, o-ethoxybenzoyl chloride and potassium thiocyanate can be used as raw materials. First, o-ethoxybenzoyl chloride and potassium thiocyanate react at 50 to 70 degrees Celsius in a polar solvent such as acetonitrile to form an intermediate of o-ethoxybenzoyl isothiocyanate. Afterwards, the intermediate is reacted with a vulcanizing agent, such as sodium sulfide or thiourea, under suitable conditions to promote molecular rearrangement and cyclization, resulting in 6-ethoxy-1,3-benzothiazole-2 (3H) -thione. The product also requires regular separation and purification methods, such as distillation, crystallization, etc., to achieve the desired purity.
