General procedure: To ethyl 3-chloroquinoxaline-2-carboxylate 1 (1 g, 4.22 mmol),appropriate acetylene derivative (3.33 mmol, 1.5 eq.) in ethanol(15 mL) was added in a two-necked flask containing triethylamine(1.4 mL, 10 mmol), Pd/C (45 mg, 0.42 mmol), triphenylphosphine(110 mg, 0.42 mmol), and CuI (50 mg, 0.26 mmol). The reaction mixture was stirred at 60 C for 5 h. After cooling, the mixture wasfiltered with celite and the filtrate diluted with dichloromethane,washed with H2O (3 x 40 mL) and dried over MgSO4. After evaporation,the crude product was purified by silica gel chromatography(CH2Cl2).
49679-45-0, 49679-45-0 Ethyl 3-chloroquinoxaline-2-carboxylate 12283436, aquinoxaline compound, is more and more widely used in various fields.
