Procedure

N-[2-(4-Benzyloxyphenoxy)ethyl]-3-(imidazol-1-yl)propylamine dihydrochloride hydrate (4.24 g) was suspended in IMS (200 ml) and methanol (10 ml) and hydrogenated at atmospheric pressure using 10% palladium/charcoal as a catalyst (0.44 g). The mixture was filtered and the filtrate evaporated to give a residue which was triturated with warm ether and filtered to give a solid which was recrystallised from methanol/ether to give 4-{2-[3-(imidazol-1-yl)propylamino]ethoxy}phenol dihydrochloride, m.p. 195-197° C.
