Reaction Steps

To a solution of 2-chloro-6-methyl-5-nitro-quinoline (350 mg, 1.57 mmol) in dioxane (6.7 mL) and water (0.7 mL) were added K2CO3 (652 mg, 4.72 mmol), trimethylboroxine (0.22 mL, 1.57 mmol) and PdCl2(dppf) (129 mg, 0.157 mmol) under Ar. The mixture was heated at 105° C. overnight, then cooled and the resulting solid was collected by filtration, washed with ethyl acetate, and dried. Purification by flash column (hexane/ethyl acetate gradient) gave 2,6-dimethyl-5-nitro-quinoline (195 mg, 61%).
