Procedure

The procedure of Example 2 was repeated with a solution of 2.00 g (10.2 mmol) 4-hydroxyphenylglyoxal dimethyl acetal in 10 g methanol containing 0.23 g (6.3) mmol) hydrogen chloride and 0.20 g moist 10% Pd/C catalyst being reacted with hydrogen ga pressurized at 170 psig at 25° C. with stirring of 550 rpm. A 53% yield of 4-(2'-methoxyethyl)phenol was obtained.

Workup

  1. custompressurized at 170 psig at 25° C.
