摘要：

3-Methoxyphenol can be selectively nitrosated in propionic acid, and the resulting slurry of 2-nitroso-5-methoxyphenol can be cleanly oxidized by nitric acid to the nitro compound. An improved procedure for the preparation of 6-Methoxy-2(3H)-benzoxazolone from this nitro compound is also presented.
