Methyl 2-mercaptobenzo[d]oxazole-6-carboxylate, cas is 72752-81-9, it is a common heterocyclic compound, the benzoxazole compound, its synthesis route is as follows.,72752-81-9

Methyl 2-chloro-l,3-benzoxazole-6-carboxylate (Intermediate B) To Compound4 (2 g, 9.5 mmol), SOCl2 (9.8 ml, 134 mmol) and DMF (0.8 niL, 10 mmol) was added at room temperature. The reaction mixture heated to reflux for 15 min. The solvent was removed under reduced pressure. The crude oil was azeotroped with xylene twice. The residue was dissolved in a minimum amount of DCM / MeOH, and then loaded onto a silica gel column, eluting with EtOAc/isohexane to give intermediate B as a white solid. H NMR (500MHz, CDC13, ppm): 4.0 (s, 3H)5 7.8 (d, IH), 8.1 (d, IH), 8.3 (s, IH). LC-MS, M+l – 212.1

With the rapid development of chemical substances, we look forward to future research findings about 72752-81-9
