With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.59-49-4,2-Benzoxazolinone,as a common compound, the synthetic route is as follows.
Ar gas protection, Ice bath conditions, NaH (910 mg, 47.9 mmol) was added to dry THF and benzoxetine was added (3.6 g, 26.6 mmol) Dissolved in anhydrous THF, Methyl iodide (5.7 g, 40 mmol) was slowly added, Reaction to ice bath to room temperature overnight reaction. After the reaction was stopped, the mixture was concentrated, diluted with water, extracted with DCM, dried and separated on a light reddish brown solid (2.8 g, 71%), 59-49-4
As the paragraph descriping shows that 59-49-4 is playing an increasingly important role.
