실험 절차
The procedure described in Example 1 is repeated using, instead of 2-aminophenol, an equivalent amount of 2-amino-4-phenylphenol in ethanol and holding the mixture under reflux in the presence of 1 ml. of trimethylamine for 60 hours. The crude product is crystallized from acetone to obtain (5-phenyl-2-benzoxazolinylidene)malononitrile of melting point ca. 236° C. (dec.).
