Reaction Steps

2-[2-(5-Methyl-4-imidazolyl-methylthio)ethylamino]-3-benzyloxy-5-methylpyridine (1.29 g, 3.5 mmole) was heated for 1 hour at 60° with conc. hydrochloric acid (excess). This mixture was then evaporated to dryness under reduced pressure and the residue was recrystallised from methanol and ethyl acetate to yield 2-[2-(5-methyl-4-imidazolylthio)ethylamino]-3-hydroxy-5-methylpyridine dihydrochloride (470 mg, 38% yield, mp 214°-216°).
