To a stirred solution of methyl 8-methyl-1-oxo-1,2,3,4-tetrahydroisoquinoline-7-carboxylate (76d, 100 mg, 0.46 mmol) in DMF (5 mL) was added NaH (0.032 g, 1.32 mmol, 60% in oil) at 0° C. under N2. After stirring at 0° C. for 30 minutes, 1-(benzyloxy)-2-(chloromethyl)-3,5-dimethylbenzene benzyl 2-(chloromethyl)-3,5-dimethylphenyl ether (Cpd Z, 180 mg, 0.69 mmol) was added and the reaction mixture stirred at room temperature overnight. The reaction mixture was poured into ice-water (20 mL). The reaction mixture was extracted with EtOAc (3×20 mL). The combined organic layers were washed with brine (2×10 mL), dried over Na2SO4, filtered, and concentrated under vacuum. The residue was purified by column chromatography (petroleum ether/EtOAc=1:1) to obtain 2-{[2-(benzyloxy)-4,6-dimethylpyridin-3-yl]methyl}-8-methyl-1-oxo-1,2,3,4-tetrahydroisoquinoline-7-carboxylic acid (76e, 120 mg, 61%) as a yellow gum.
