Procedure

A mixture of 2.0 g of 1-(4-benzyloxyphenyl)-2-[2-(N,N-dimethylamino)ethoxy]ethanol hydrochloride, 500 mg of 10% palladium-carbon and 10 ml of methanol was subjected to hydrogenation for 2 hours at room temperature under atmospheric pressure. After the completion of the reaction, palladium-carbon was removed by filtration. The solvent was removed by distillation under reduced pressure to obtain 1.4 g of 1-(4-hydroxyphenyl)-2-[2-(N,N-dimethylamino)ethoxy]ethanol hydrochloride (Compound No. 170).
