As a common heterocyclic compound, it belongs to benzoxazole compound, name is Benzo[d]oxazol-6-amine, and cas is 177492-52-3, its synthesis route is as follows.
A solution of benzo[djoxazol-6-amine (0.500 g, 3.727 mmol), methanesulfonyl chloride (0.317 mL, 4.100 mmol) and triethylamine (0.779 mL, 5.591 mmol) in dichloromethane (3 mL) was stirred at the room temperature for 3 hr. Then, water was added to the reaction mixture, followed by extraction with dichloromethane. The organic layer was washed with aqueous saturated sodium chloride solution, dried with anhydrous Mg504, filtered, and concentrated in vacuo. The residue was chromatographed (5i02, 4 g cartridge; ethyl acetate / hexane = 0 % to 50 %) to give N(benzo[djoxazol-6-yl)methanesulfonamide as purple solid (0.351 g, 44.4 %).
177492-52-3, 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.,177492-52-3 ,Benzo[d]oxazol-6-amine, other downstream synthetic routes, hurry up and to see
