With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.36958-61-9,5-(Bromomethyl)-3-methylisoxazole,as a common compound, the synthetic route is as follows.
Sodium hydride (60% w/w) (34.1 mg, 0.85 mmol) was added to a stirring solution of 7-benzylsulfanyl-4-(cyclopropanecarbonyl)-2H-isoquinolin-1 -one (220. mg, 0.66 mmol) in DMF (8 mL). After 15 min 5-(bromomethyl)-3-methyl-1 ,2-oxazole (0.15 mL, 0.85 mmol) was added and the reaction mixture stirred at ambient temperature for 1 h. DCM (25 mL) and saturated aq. NaHC03 (25 mL) were added and the mixture stirred for 5 min. The DCM layer was isolated by passing through a hydrophobic frit and the aqueous layer washed with DCM. The combined DCM extracts were concentrated under reduced pressure and purified by automated column chromatography, SiO2, eluent 0-100% EtOAc in iso- Hexane to yield 7-benzylsulfanyl-4-(cyclopropanecarbonyl)-2-[(3-methylisoxazol-5- yl)methyl]isoquinolin-1 -one (263 mg, 0.61 mmol, 93%). Used directly in the synthesis of Intermediate S10-C1, 36958-61-9
As the paragraph descriping shows that 36958-61-9 is playing an increasingly important role.
