With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.701-16-6,5-Fluoro-2-methylbenzo[d]oxazole,as a common compound, the synthetic route is as follows.
701-16-6, 5-Fluoro-2-Methyl-6-Nitrobenzoxazole (10) Concentrated sulfuric acid (60 mL) was stirred mechanically and cooled in an ice/water bath. To this was gradually added 5-fluoro-2-methylbenzoxazole (9), (20 g, 0.132 Moles), at such a rate that the temperature stayed at 15-20 C., over a 15-20 minute period. A solution of concentrated sulfuric acid (11 mL), and concentrated nitric acid (10 mL), was prepared and added drop by drop to the benzoxazole solution at such a rate that the temperature was maintained at approximately 10 C.
701-16-6 5-Fluoro-2-methylbenzo[d]oxazole 2769350, abenzoxazole compound, is more and more widely used in various fields.
