Reaction Steps

In a sealed tube, 3-bromopyridine (0.1 g, 0.633 mmol) was combined with 6-chloro-3,4-dihydroisoquinolin-1(2H)-one (intermediate A-2) (0.115 g, 633 mmol), copper (I) iodide (0.012 g, 0.063 mmol), potassium carbonate (0.175 g, 1.27 mmol) and N,N′-dimethylethylenediamine (0.013 g, 0.127 mmol) in 1,4-dioxane (2 mL). The reaction mixture was heated at 110° C. overnight. The mixture was cooled to room temperature, filtered through dicalite and washed with DCM. The residue was purified by silica gel flash chromatography eluting with a 5 to 100% EtOAc-heptane gradient to give the title compound (0.107 g, 65%) as a white solid. MS: 259.1 (M+H+).
