As a common heterocyclic compound, it belong benzoxazole compound,Methyl 2-mercaptobenzo[d]oxazole-6-carboxylate,72752-81-9,Molecular formula: C9H7NO3S,mainly used in chemical industry, its synthesis route is as follows.,72752-81-9
Step 1: To a stirred mixture of methyl 2-mercaptobenzo[d]oxazole-6-carboxylate (5 g, 23.92 mmol) and solidK2CO3 (9.9 g, 71.76 mmol) in anhydrous DMF (50 mL) at rt was added methyl iodide (10.2 g, 71.76 mmol). The mixturewas stirred at rt for 15 h. The reaction mixture was diluted with water then extracted with DCM (3 3). The combinedorganic layers were washed with water and 2 M aq HCl. The organic layer was separated and dried over MgSO4 filtered,and concentrated under reduced pressure to afford methyl 2-(methylthio)benzo[d]oxazole-6-carboxylate (4.24 g, 80%)as a light pink solid that did not require further purification. 1H NMR (300 MHz, CDCl3) delta 8.12 (d, J = 1.1 Hz, 1H), 8.04(dd, J = 1.1,8,3 Hz, 1H), 7.61 (d, J = 8.3 Hz, 1H), 3.95 (s, 3H), 2.79 (s, 3H). LCMS (ESI) m/z 224 (M + H)+.
With the synthetic route has been constantly updated, we look forward to future research findings about Methyl 2-mercaptobenzo[d]oxazole-6-carboxylate,belong benzoxazole compound
