3-(4-Chlorobenzyloxy)-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthylboronic acid → 3-{4-hydroxy-3-[3-(4-chlorobenzyloxy)-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthyl]phenyl}acrylic Acid

Participants

Reaction Steps

In a manner similar to that of Example 1(c), by reaction of 1.0 g (3.7 mmol) of ethyl 3-(3-bromo-4-hydroxyphenyl)acrylate obtained in Example 34(d) with 2.05 g (5.5 mmol) of 3-(4-chlorobenzyloxy)-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthylboronic acid obtained above, 590 mg (30%) of the expected compound were obtained in the form of a white solid having a melting point of 152°-154° C.
