Cysteamine. HCI

In an initial step, 2-chloroacetic acid ethyl ester is reacted with formamide to give 5-methylimidazole-4-carboxylic acid ethyl ester. Then sodium in ammonia is used to convert that to 4-hydroxymethyl-5-methylimidazole-hydrochloride. Cysteamine HCI (HSCH2CH2NH2-HCI) is then reacted to give 4-(2-aminomethyl)-thiomethyl-5-methyl-imidazole dihydrochloride. Then N-cyanamido-5,5-dimethyl-dithio-carbonate (from cyanamid, KOH, CS2 and ((CH3)2S04) is reacted to give a further intermediate which is finally reacted with methylamine to give cimetidine. [Pg.1022]
