실험 절차

A mixture of 274 g 4-benzoyloxybiphenyl (see Example 1) and 2000 ml glacial acetic acid is heated to 85° C. Then, 650 ml fuming nitric acid is dripped in such a manner that the temperature does not drop below 90° C. After cooling, the precipitate is filtered off, washed neutral with water and recrystallized from glacial acetic acid (melting point: 214° C.); yield: 60%.
