A suspension of 48 g. of 4'-(ethylamino)-3',5'-dimethoxy-2-(methylsulfonyl)acetophenone and 23.8 g. of sodium borohydride in 1 liter of alcohol was stirred at room temperature for 20 hours, resulting in a solution. After the addition of 1 liter of water, the alcohol was evaporated under vacuum. The crystals formed were removed by filtration with suction, washed with water and dried, whereby there was obtained 4-(ethylamino)-3,5-dimethoxy-α-[(methylsulfonyl)-methyl]-benzyl alcohol having a melting point of 121°-122° C.
