Versuchsvorschrift

By a procedure similar to that of Example I, the above compound (3.9 g., m.p. 170°-173° C.) was prepared from 3.8 g. (0.025 m.) of p-hydroxyphenylisothiocyanate and 3.2 g. (0.025 m.) of cyclohexylisocyanate, using 50 mls. of benzene as a solvent and 3 drops each of triethylamine and dibutyltin dilaurate as catalysts.
