Reaction Steps

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 1-bromo-3-phenylpropane (167 μL). The reaction mixture is allowed to stir at room temperature for 72 h. The reaction mixture is poured into water (25 mL) and extracted with EtOAc (2×25 mL). The organic layer is dried (Na2SO4) and concentrated. The resulting crude solid is purified by recrystallization from ethanol to afford 277 mg (52%) of the title compound as a white solid.
