Procedure
In a manner similar to that of Example 1(c), by reaction of 1.0 g (3.5 mmol) of ethyl 3-(3-bromo-4-methoxyphenyl)acrylate obtained in Example 13(d) with 1.54 g (5.26 mmol) of 2-propyloxy-3,5-di-tert-butylphenylboronic acid obtained in Example 39(b), 1.20 g (76%) of the expected compound was obtained in the form of a white powder having a melting point of 107°-109° C.
