Hydrazine hydrate (0.62 mL) was added and the reaction mixture was refluxed for 1 h. The solvent was removed in vacuo and the residue dissolved in dichloromethane. The insoluble residue was filtered off and purified by silica gel chromatography (Merck SuperVarioPrep 70 g column, Si60 15-40 μm), eluted with methanol/dichloromethane, 20:80 then ammonium hydroxide/methanol/dichloromethane, 0.5:25:75 to give 1-(3-amino-propyloxy)-3,5-bis-(hydroxy-methyl)-benzene (1 g) suitable for further transformation.
