With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.3622-35-3,Benzo[d]thiazole-6-carboxylic acid,as a common compound, the synthetic route is as follows.
General procedure: Carboxylic acids (1 mmol) and 1,1′-carbonyl diimidazole(1 mmol) were taken in THF (15 mL) in a round-bottommed flask(100 mL) and stirred for 30 min in order to activate the carboxylicacids. Then metronidazole (1 mmol) was added into the reactionmixture with constant stirring for 24 h. Reaction progress wasmonitored by TLC (6:4 EtOAc:Hexane). Reaction mixture waspoured onto crushed ice (100 mL), precipitates appeared immediatelywhich were filtered and dried in air. The precipitates werecrystallized from ethanol. Products were characterized by spectroscopictechniques such as EIMS, 1H NMR and 13C NMR. CHNanalysis was also performed.
3622-35-3, As the paragraph descriping shows that 3622-35-3 is playing an increasingly important role.
