49679-45-0, Ethyl 3-chloroquinoxaline-2-carboxylate is a quinoxaline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
(1) To a solution of ethyl 3-chloroquinoxaline-2-carboxylate (see J. Chem. Soc. 1945, 622; 12.3 g, 52.0 mmol) and triethylamine (8.70 mL, 62.4 mmol) in N,N-dimethylformamide (52 mL) was added aqueous dimethylamine (50%, 6.60 mL, 62.7 mmol) at room temperature. After being stirred for 3 hour at room temperature, the reaction mixture was poured into water (500 mL), and the mixture was extracted with ethyl acetate (2000 mL). The organic layer was washed with water, dried over sodium sulfate, filtrated and concentrated in vacuo. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=4:1) to give ethyl 3-(dimethylamino)quinoxaline-2-carboxylate as a pale yellow oil (12.6 g, 99%). MS (APCI): m/z 246 (M+H).
49679-45-0, 49679-45-0 Ethyl 3-chloroquinoxaline-2-carboxylate 12283436, aquinoxaline compound, is more and more widely used in various fields.
