Procedure

A mixture of 4′-{[2-ethyl-4-hydroxy-6-oxo-5-(2-phenylethyl)thieno[2,3-b]pyridin-7(6H)-yl]methyl}biphenyl-2-carbonitrile (0.5 g), iodomethane (0.076 mL), 60% sodium hydride (0.049 g) and tetrahydrofuran (15 mL) was stirred at room temperature for 20 hr. The reaction mixture was diluted with ethyl acetate, washed successively with 5% aqueous potassium hydrogensulfate solution and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give the title compound as a colorless amorphous solid (0.32 g, 62%).
