Procedure
To a stirred suspension of 3.35 g of 4-chloro-5-nitrothieno[2,3-b]pyridine 7 in 160 ml of 2-propanol is introduced excess amount of anhydrous ammonia at 45°-50° C. during 4 hours. After removal of the solvent, the residue is suspended in water. The solid is washed with water and cold ether, affording 2.65 g (87%) of Compound 8 as crystals. Recrystallization from methanol-ether gives a pure sample melting at 227°-228.5° C.
