0.01 mole (2.65 g) of 1-[bis(hydroxymethyl)-methyl]-6,7-dimethoxy-3,4-dihydroisoquinoline is dissolved in 50 ml of ethanol, and the mixture is reduced in hydrogen atmosphere, in the presence of a 10% platinum-on-activated carbon catalyst, under normal conditions. After uptake of the calculated amount of hydrogen (1 to 2 hours), the catalyst is filtered off and the filtrate is evaporated to yield the aimed compound in crystalline form.
