To a sodium propan-1-olate solution, prepared by addition of sodium (36 mg, 1.58 mmol) to propanol (1 mL), was added 2,6-dibromopyridine (250 mg, 1.06 mmol). The mixture was stirred at 90° C. for 2 h, then was diluted with EtOAc. The organic phase was washed with water (2×) and brine, dried (Na2SO4) and concentrated. The crude material was purified by flash chromatography (0 to 10% EtOAc/hexanes gradient) to afford 189 mg of Intermediate 161.1 as a colorless oil. LCMS (2 min gradient) RT=1.82 min, 216.1 (M+H)+.
