The 5-bromo-3-(1-BOC-2-(S)-azetidinylmethoxy)pyridine from Example 54b (400 mg, 1.2 mmol), 3-aminophenylboronic acid (361 mg, 2.3 mmol, Aldrich Chem. Co.), Pd(0) (35 mg) and Na2CO3 (1.5 mL of a 2M solution) were mixed in 8 mL of toluene, and the mixture was stirred at reflux for 16 hours. The solvent was removed under vacuum, and the residue was purified by chromatography on silica gel, eluting with exane:ether 1:1, to afford 178 mg of the title compound.
