실험 절차

To a solution of 3-(1-BOC-2-(R)-azetidinylmethoxy)-6-chloro-5-bromopyridine (660 mg, 1.75 mmol) in toluene (20 mL) was added NEt3 (0.7 mL), copper (I) iodine (33 mg), tetrakis(triphenylphosphine)palladium (0) (201 mg) and (trimethylsilyl)acetylene (0.30 mL, 2.10 mmol). The reaction mixture was stirred and heated at 100° C. for 16 h. Solvent was evaporated and the residue was chromatographed (silica gel; hexane/EtoAc, 5:1 to 2:1) to afford an oil (430 mg, 62%): 1H NMR (CDCl3, 300 MHz) δ 1.42 (s, 9H), 2.20-2.40 (m, 2H), 3.80-3.92 (m, 2H), 4.10 (m, 1H), 4.30 (m,1H), 4.50 (m, 1H), 7.37 (d, (H, J=3.0 Hz), 8.05 (d, 1H, J=3.0 Hz); MS (CI/NH3) m/z 395 (M+H)+.
