반응 단계
o-Nitrophenyl phenyl ether was reduced catalytically to o-phenoxyaniline, m. 43°-5°, which was acetylated to 2'-phenoxyacetanilide, m. 82°-4°. Yields from both reactions were essentially quantitative. The 2'-phenoxy-acetanilide was dissolved in acetic acid and treated at 60°-80° with red fuming nitric acid to produce a 60-70% yield of 4'-nitro-2'-phenoxy-acetanilide, m. 176°-183°. This was deacetylated by refluxing with methanolic hydrochloric acid to 4-nitro-2-phenoxyaniline, m. 116°-8°. The yield was 99% of theoretical.
