Procedure

N-(4-Chlorobenzyl)-4-hydroxy-2-(4-morpholinylmethyl)thieno[2,3-b]pyridine-5-carboxamide (418 mg) from Example No. 41 and potassium carbonate (152 mg) are suspended in DMF (10 mL) and to the mixture is added iodoethane (88 μL). The reaction mixture is allowed to stir at room temperature for 24 h. The resulting suspension is poured into water (25 mL), filtered, and washed with water (5 mL) followed by diethyl ether (5 mL). The resulting crude solid is purified by recrystallization from ethanol to afford 325 mg (73%) of the title compound as a white solid.
