Procedure
To a solution of 28% sodium methoxide (1.11 mL) and methanol (5.5 mL) was added dropwise a solution of 2-chloro-5,6-dimethyl-3-nitropyridine (1-013-05) (837 mg) in methanol (6.6 mL) for 5 min at room temperature under nitrogen atmosphere, and the reaction mixture was heated with stirring, in oil-bath at 50° C. for 7 h. To the reaction mixture was added diethyl ether and the reaction mixture was poured into water, extracted with twice with diethyl ether, washed once with water, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give 5,6-dimethyl-2-methoxy-3-nitropyridine (1-013-06) (675 mg, 82.6%, m.p.: 71-73° C.) as an orange crystal.
