Procedure

In ethanol (50 ml) was dissolved 2-(N-methyl-N-(4-nitrobenzyl)amino)-1,3-propanediol (2.9 g), and catalytic reduction was carried out with 5% palladium carbon (0.15 g) at room temperature for 2 hours. The catalyst was filtered off, and the solvent of the filtrate was evaporated. The residue was purified with silica gel column (methanol/triethylamine/ethyl acetate) to give 2-(N-(4-aminobenzyl)-N-methylamino)-1,3-propanediol (0.6 g) as pale yellow amorphous.
