Versuchsvorschrift
A mixture of 117 parts of 2-(methoxymethyl)-1,4-bis(phenylmethyl)piperazine and 400 parts of methanol was hydrogenated at normal pressure and at room temperature with 5 parts of palladium-on-charcoal catalyst 10%. After the calculated amount of hydrogen was taken up, the catalyst was filtered off and the filtrate was evaporated. The residue was distilled, yielding 38.6 parts (78.8%) of 2-(methoxymethyl)piperazine; bp. 75°-80° C. (intermediate 31).
