Procedure

The procedure of Preparation Example 2 was repeated, except that 224 mg of (2Z)-2,3-bis(4-methoxyphenyl)prop-2-enenitrile was used in place of 4′-methoxy-2-biphenylacetonitrile, and 1,2-dichloroethane was used in place of methylene chloride. The resulting crude product was purified by TLC (using a 3:1 mixture of chloroform and acetone as the developing solvent) to obtain 130 mg of (2Z)-2,3-bis(4-hydroxyphenyl)-prop-2-enenitrile.
