Versuchsvorschrift
A suspension of the product from step (c) (1.3 g) and 10% w/w Pd/C (1.0 g) in 30% w/w ethanolic dimethylamine (25 ml) was hydrogenated for 24 hours and filtered through Hyflo. Fresh Pd/C (0.7 g) and ethanolic dimethylamine (5 ml) were added to the filtrate and hydrogenation continued for a further 16 hours. The mixture was filtered through a silica column using DCM/EtOH/NH4OH (40:8:1) as eluant to give the desired product as a colourless foam (0.3 g). Elemental analysis and 1H NMR were consistent with the proposed structure.
