A mixture of benzyl 4-(2-oxo-1,2-dihydropyridin-4-yloxy)piperidine-1-carboxylate (697 mg, 2.12 mmol), (4-bromophenyl)(methyl)sulfane (431 mg, 2.12 mmol, Aldrich), quinolin-8-ol (61.6 mg, 0.425 mmol, Alfa Aesar), potassium carbonate (381 mg, 2.76 mmol, EMD), Copper(I) iodide (81 mg, 0.43 mmol, Alfa Aesar) in DMSO (6 mL) was stirred at 145° C. overnight under Argon. The resulting mixture was diluted with H2O and extracted with EtOAc (2×). The combined organic layers were washed with brine, dried over Na2SO4 and concentrated in vacuo to a green solid. The solid was purified by flash chromatography (SiO2, 0 to 5% MeOH in CH2Cl2) to yield 911 mg of desired product as a light green solid. MS (ESI) 451 (M+H).
