Reaction Steps

12.71 g (0.0459 mole) of 2-chloromethyl-3-methyl-4-(2,2,2-trifluoroethoxy)pyridine hydrochloride were suspended in 322 ml of acetone in the presence of 2.52 ml N,N-dimethylacetamide. Then 7.24 g (0.0597 mole) of 2-mercaptobenzimidazole were added. The mixture was heated to reflux and stirred for 5 hours.
