To a stirred solution of 8-methyl-5-(1-methyl-1H-pyrazol-4-yl)-7-(propan-2-yloxy)-3,4-dihydroisoquinolin-1(2H)-one (108j, 60 mg, 0.2 mmol) in DMF (5 mL) was added NaH (9.6 mg, 0.4 mmol, 60% in oil) at 0° C. under N2. After 30 minutes, 1-(benzyloxy)-2-(chloromethyl)-3,5-dimethylbenzene benzyl 2-(chloromethyl)-3,5-dimethylphenyl ether (Cpd Z, 115 mg, 0.44 mmol) was added and stirred at room temperature for 14 hours. The reaction mixture was poured into ice-water (20 mL), then 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 give 2-{[2-(benzyloxy)-4,6-dimethylpyridin-3-yl]methyl}-8-methyl-5-(1-methyl-1H-pyrazol-4-yl)-7-(propan-2-yloxy)-3,4-dihydroisoquinolin-1(2H)-one (108k, 40 mg, 38%) as a white solid.
