Versuchsvorschrift

The urea was prepared from 2-hydroxy 4-trifluoromethyl aniline(example 7a, 0.171 g, 1 mmol)) and 2-phenyl phenyl isocyanate by general Method B. It was purified by dilution with methylene chloride and precipitation with hexane. Filtering afforded the desired compound(0.24 g, 64%). EI-MS m/z 373(M+H)+
