2-Amino-3-benzoyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine (2 mmol), as prepared in Example 8, and methyl iodide (3 mmol) were dissolved in dry dimethyformamide (20 mL). Finely ground anhydrous potassium carbonate (1.9 g) and sodium iodide (0.2 g) were added to the solution and the resulting mixture was warmed to 65° C. overnight under nitrogen. After this period (TLC control), the reaction mixture was cooled, diluted with water, extracted with diethyl ether (3×50 mL), and dried on sodium sulfate. The crude product was isolated and then purified by column chromatography eluting with ethyl acetate and petroleum ether solutions to give the desired compound. (m.p. 164-165° C.; 77% yield).
