Procedure
In a manner similar to that of Example 2(g), by reaction of 10.1 g (20.3 mmol) of ethyl 3-(3-bromo-4-methoxymethoxyphenyl)acrylate obtained in Example 2(c) with 5.4 ml (102 mmol) of 98% sulfuric acid, 3.9 g of ethyl 3-(3-bromo-4-hydroxyphenyl)acrylate (49%) were obtained in the form of a white powder having a melting point of 112°-3° C.
