Reaction Steps

To a suspension of 1.82 g of 2-mercaptobenzimidazole and 6.7 g of K2CO3 in 35 ml of DMF was added 2.4 g of 7-chloromethyl-3-methylthieno[2, 3-c]pyridine, and the mixture was stirred for 2 hr. DMF was evaporated under reduced pressure, and CHCl3 was added to the residue for extraction. The CHCl3 layer was washed with water and dried. Then, CHCl3 was removed by evaporation, and ether was added to he residue, whereby 3.41 g (Yield : 90.5%) of the objective product (Ia-11), 2-[(3-methylthieno[2, 3-c]pyridin-7-yl)methylthio]benzimidazole was obtained as crystals.
