실험 절차

Sodium (0.46 g) is dissolved in absolute methanol (50 ml) and the resultant solution of sodium methoxide is added to a solution of 2-chloro-4-nitropyridine-1-oxide (3.5 g, prepared as described in Example 1) in methanol (10 ml). The reaction mixture is allowed to stand at room temperature for 50 hours and is then subjected to rotary evaporation to give 2-chloro-4-methoxypyridine-1-oxide.
