Reaction Steps

A solution of 8-chloro-7-(1-methyl-1H-pyrazol-5-yl)-3,4-dihydroisoquinolin-1(2H)-one (66b, 48.0, 0.180 mmol), 2-(benzyloxy)-3-(chloromethyl)-4,6-dimethylpyridine (Cpd Z, 71.7 mg, 0.274 mmol), and KHMDS (182 mg, 0.915 mmol) in 1,4-dioxane (5 mL) was heated at 80° C. overnight. To the reaction mixture was added H2O (10 mL), the solution was extracted with EtOAc (10 mL), the organic layer concentrated under vacuum, and the residue purified by prep chromatography to give 2-{[2-(benzyloxy)-4,6-dimethylpyridin-3-yl]methyl}-8-chloro-7-(1-methyl-1H-pyrazol-5-yl)-3,4-dihydroisoquinolin-1(2H)-one (66c, 60 mg, 67%) as a colorless oil.
