Sodium Carbonate → 5-Phenyl-3-(1-BOC-2-(S)-azetidinylmethoxy)pyridine

Participants

Reaction Steps

The 5-bromo-3-(1-BOC-2-(S)-azetidinylmethoxy)pyridine from Example 54b (1.03 g, 3 mmol), phenylboronic acid (920 mg, 7.5 mmol), Pd(0) (100 mg) and Na2CO3 (4 mL of a 2 M solution) were mixed in 20 mL of toluene, and the mixture was stirred at reflux for 3 hours. The solvent was removed under vacuum, and the residue was purified by chromatography on silica gel, eluting with CHCl3 :MeOH 100:2, to afford 1.39 g of the title compound. MS (CI/NH3) m/z 341 (M+H)+. 1H NMR (CDCl3, 300 MHz) δ1.38 (s, 9H), 2.32 (m, 2H), 3.89 (m, 2H), 4.21 (m, 1H), 4.41 (m, 1H), 4.54 (m, 1H), 7.40 (m, 3H), 7.50 (m, 2H), 8.10 (m, 1H), 8.54 (m, 1H), 8.20 (m, 1H).
