2382-96-9, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,2382-96-9 ,Benzo[d]oxazole-2-thiol, other downstream synthetic routes, hurry up and to see

As a common heterocyclic compound, it belongs to benzoxazole compound, name is Benzo[d]oxazole-2-thiol, and cas is 2382-96-9, its synthesis 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%.
