Reaction Steps

To a mixture of 3-(1-BOC-2-(S)-azetidinylmethoxy)-5-bromopyridine (0.42 g, 1.2 mmol), tetrakis(triphenylphosphine)palladium(0) (40 mg, 0.034 mmol), sodium carbonate (2.0 M, 2 mL) in toluene (10 mL) was added 2-thienylboronic acid (0.38 g, 3.0 mmol). The reaction mixture was stirred and heated at 80° C. for 16 h. Solvent was evaporated. The residue was chromatographed (silica gel; hexane/EtOAC, 10:1 to 2:1) to afford an oil (0.24 g, 57%): 1H NMR (CDCl3, 300 MHz) δ1.42 (s, 9H), 2.26-2.90 (m, 2H), 3.86-3.94 (m, 2H), 4.20 (m, 1H), 4.39 (m, 1H), 4.55 (m, 1H), 7.12 (m, 1H), 7.36 (s, 1H), 7.44 (s, 1H), 8.26 (s, 1H), 8.50 (s, 1H); MS (CI/NH3) m/z 347 (M+H)+.
