Procedure
7 g of 2-[1,1-dimethyl-2-(2,6-dimethylhydroxyphenyl)ethylamino]-1-(3,4-dibenzyloxy-2-methylphenyl)ethanone hydrochloride in 125 mL of methanol is hydrogenated using 2 g of palladium on charcoal (5%). After separation of the catalyst, the solvent is distilled off. The solid that crystallizes out is stirred into acetonitrile, suction filtered, and washed. Yield: 3.5 g of hydrochloride; melting point: 182° C.–183° C. (decomposition).
