실험 절차

To a solution of 3-(1-BOC-2-(S)-pyrrolidinylmethoxy)-5-bromo-6-chloropyridine (1.64 g, 4.20 mmol) and 4-chlorophenylboronic acid (620 mg, 3.9 mmol.) in toluene (20 mL) was added Pd(0) (97 mg) and Na2CO3 (5 mL of a 2 M solution), and the mixture was heated at reflux for 16 h. The reaction mixture was quenched with saturated NaHCO3 solution and extracted with Et2O. The solvent was removed under vacuum, and the residue was chromatographed (silica gel; EtOAc/hexane, 1:4) to afford the title compound (430 mg, 24% yield): 1H NMR (CDCl3, 300 MHz) δ 1.45 (s, 9H), 1.83-2.00 (m, 4H), 3.30-3.45 (m, 2H), 4.00 (m, 1H), 4.06-4.25 (m, 2H), 7.36-7.46 (m, 5H), 8.10 (s, 1H); MS (CI/NH3) m/z 423 (M+H)+.
