Versuchsvorschrift

By a procedure similar to that of Example I, the above compound (5.2 g., m.p. 139°-142° C.) was prepared from 7.6 g. (0.05 m.) of p-hydroxyphenylisothiocyanate and 6.0 g. (0.05 m.) of phenyl isocyanate, using 35 mls. of benzene as a solvent and 2 drops each of triethylamine and dibutyltin dilaurate as catalysts.
