A mixture of 3-chloro-N-methoxy-N-methylquinoxaline-6-carboxamide (5 g, 0.02 mol, 1.0 eq.), (4-chlorophenyl)boronic acid (3.43 g, 0.022 mol, 1.1 eq.) Pd(dppf)2C12 (816 mg, 0.001 mol, 0.05 eq.) and Na2CO3 (4.24 g, 0.04 mol, 2.0 eq.) in dioxane and water (90 mL/10 mL) was heated at 80° C. for 4 hs under N2 protection, then cooled and concentrated. The resulting residue was purified by flash column chromatography (PE/EA=4/1, v/v) to afford 3-(4-chlorophenyl)-N-methoxy-N-methylquinoxaline-6-carboxamide (4 g, 61.0%).
