With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2382-96-9,Benzo[d]oxazole-2-thiol,as a common compound, the synthetic route is as follows.
Specifically include:Solid phosgene (BTC) is selected as the chlorinating agent.2 mmol of 2-mercaptobenzoxazole prepared in the step 1 was added to the flask.Add 10 mL of toluene or cyclohexane as solvent to the flask.4 mmol of solid triphosgene was added to the flask.Warm up to 50 C under magnetic stirring, keep warm for 10 min, and then slowly heat up.Each temperature is raised at 10 C for 10 min, when the temperature is raised to 105 C, the temperature is kept for 1 h; TCL point plate analysis,Properly extend the reaction time,After separation by column chromatography, 0.142 g of 2-chlorobenzoxazole was obtained.The product was slightly yellowish liquid with a yield of 46%., 2382-96-9
The synthetic route of 2382-96-9 has been constantly updated, and we look forward to future research findings.
