2-Methoxy-5-nitropyridine CAS 5446-92-4 yog tau los ntawm etherification ntawm 2-chloro-5-nitropyridine. Sodium methoxide tau ntxiv dropwise rau qhov sib tov ntawm 2-chloro-5-nitropyridine thiab methanol nyob rau hauv stirring, thiab muaju tau precipitated nyob rau hauv crushed dej khov tom qab ntxiv sulfur rau 1 h. Lim, qhuav, thiab recrystallize nrog methanol kom tau cov khoom tiav. Cov txiaj ntsig yog 92%.
