Reaction Steps

To a solution of sodium (1.65 g) in ethanol (75 ml) was added cysteamine hydrochloride (2.9 g) and after stirring for 5 minutes a solution of 2-chloromethyl-3-methoxypyridine hydrochloride (4.5 g) in ethanol (75 ml) was added over 25 minutes. The mixture was stirred for 2 hours at 15° and the sodium chloride was filtered off and the filtrate was evaporated to give 2-[2-aminoethylthiomethyl]-3-methoxypyridine (4.6 g) as a colourless oil.
