実験手順

9 g of 1-(3,4-dihydroxy-2-methoxyphenyl)-2-[1,1-dimethyl-2-(2,4,6-trimethylphenyl)-ethylamino]ethanone hydrochloride is hydrogenated with 0.4 g of platinum(IV) oxide in 125 mL of methanol. The catalyst is filtered off and the solvent is distilled off under reduced pressure. The residue is dissolved in 50 mL of ethyl acetate and the precipitated crystals are suction filtered and washed with diethyl ether and ethyl acetate. Yield: 6 g (67%, hydrochloride); melting point: 98° C.-105° C.
