Reaction Steps

In the same manner as in Example 7A, the compound obtained in Example 54A and activated manganese dioxide were reacted to yield ethyl 2-diethylaminomethyl-4-(3,4-dimethoxyphenyl)thieno[2,3-b:4,5-c']dipyridine-3-carboxylate, which was then recrystallized from ethyl acetate-hexane to yield colorless prismatic crystals having a melting point of 141 to 142° C.
