With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.20197-75-5,Methyl 1,4-Benzodioxan-6-carboxylate,as a common compound, the synthetic route is as follows.
(2) Synthesis of Compound 1 (0146) The compound k (2.01 g), NBS (8.48 g), and carbon tetrachloride (125 ml) were introduced to an eggplant-shaped flask. Then, AIBN (340 mg) was added thereto in a nitrogen atmosphere and heated to reflux for 44 hours. The reaction solution was extracted with chloroform. Subsequently, the extract was washed with saturated saline, dehydrated with sodium sulfate, and concentrated. The concentrate was purified by silica gel column chromatography (Wakosil? C-300) using chloroform alone as an eluent. Thus, the compound 1 was obtained (yield: 2.64 g; yield rate: 73percent).
20197-75-5, As the paragraph descriping shows that 20197-75-5 is playing an increasingly important role.
