Reaction Steps

To 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), diisopropylethylamine (0.72 mL), methanol (2 mL) and acetonitrile (18 mL) was added trimethylsilyldiazomethane (2M hexane solution, 0.72 mL), and the mixture was stirred at room temperature for 6 hr. The reaction mixture was concentrated under reduced pressure, and the obtained residue was extracted with water and ethyl acetate. The obtained ethyl acetate layer was washed with 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 (0.28 g, 62%).
