With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.22876-19-3,5-Chlorobenzo[d]oxazole-2(3H)-thione,as a common compound, the synthetic route is as follows.
Step 6) Synthesis of 2, 5-dichlorobenzo [d] oxazoleA mixture of 5-chlorobenzo [d] oxazole-2-thiol (3.01 g, 16.22 mmol) , sulfoxide chloride (20 mL, 272.6 mmol) and N, N-dimethylformamide (0.10 mL, 1.3 mmol) was heated to reflux and stirred for 3 hours The reaction mixture was cooled and the solvent was removed in vacuo. The resulting product was used directly in the next step., 22876-19-3
The synthetic route of 22876-19-3 has been constantly updated, and we look forward to future research findings.
