4-Propyloxy-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthylboronic acid → 3-[4-hydroxy-3-(5,5,8,8-tetramethyl-4-propoxy-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 1.61 g (5.5 mmol) of 4-propyloxy-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthylboronic acid obtained in Example 43(c), 640 mg (40%) of the expected compound were obtained in the form of a white powder having a melting point of 114°-116° C.
