Sodium Methoxide → HCID 66918098, compound

Participants

Reaction Steps

To 3-amino-2-chloro-6-methoxyquinoxaline (1.50 g, 7.16 mmol) dissolved in tetrahydrofuran (60 ml), 25 wt % sodium methoxide (15.5 g, 71.6 mmol) in methanol was added at room temperature and stirred further at room temperature for 21 hours. The resulting mixture was concentrated under the reduced pressure to remove the solvent. The product was extracted with dichloromethane and the organic layer was washed with water and dried over MgSO4. After concentration under the reduced pressure, the crude product was purified by SiO2 column chromatography. Extraction of the residue with a n-hexane:ethyl acetate (2:1) mixture and concentration gave 1.18 g of the titled compound (yield, 80%).
