Reaction Steps
2-Chlorobenzimidazole is reacted with 2-bromoacetyl-4-ethylthio-3-methylpyridine in the presence of K2CO3 to give 2-chloro-1-[2-[4-ethylthio-3-methylpyridyl])-2-oxoethyl]benzimidazole. This is reacted with thiourea and treated with NH4OH to give 2-mercapto-1-(2-(2-(4-ethylthio-3-methylpyridyl))-2-oxoethyl)benzimidazole
