Reaction Steps

To a solution of 3-benzyloxy-5-bromo-1-(2,2-dimethoxyethyl)-4-oxo-1,4-dihydropyridine-2-carboxylic acid 3-chlorobenzylamide (70 mg) obtained in Example 161, Step 2 in dimethoxyethane (1.4 ml)-water (0.7 ml) were successively added phenylboronic acid (32 mg), tetrakis(triphenylphosphine)palladium(0) (31 mg) and sodium carbonate (42 mg), and the mixture was stirred at 80° C. for 2 hr. After cooling to room temperature, the mixture was purified by silica gel column chromatography (ethyl acetate:hexane=1:3–1:1) to give 3-benzyloxy-1-(2,2-dimethoxyethyl)-4-oxo-5-phenyl-1,4-dihydropyridine-2-carboxylic acid 3-chlorobenzylamide (56 mg).
