실험 절차

A mixture of ethyl 2-bromo-7-ethyl4-oxo-4,7-dihydrothieno[2,3-b]pyridine-5-carboxylate (Eur. J. Med. Chem. 1987, 22, 139) (0.500 g) and 4-chlorobenzylamine (1.84 mL) is stirred at 190° C. for 1 h. The reaction is then allowed to cool to rt and is diluted with toluene. The resulting precipitate is filtered off and washed with toluene followed by hexanes to yield a tan solid. This material is recrystallized from acetic acid/water then ethanol to yield 0.379 g (59%) of the title compound as a white, crystalline solid.
