실험 절차

To a solution of 5-bromo-6-chloro-3-(1-BOC-2-(R)-pyrrolidinylmethoxy)pyridine from Example 69a (520 mg, 1.33 mmol) and 3-aminophenylboronic acid (310 mg, 2.0 mmol) in toluene (8mL) was added Pd(0) (50 mg) and Na2CO3 (2.5 mL of a 2M solution), and the mixture was heated at reflux for 16 hours. The solvent was removed under vacuum, and the residue was purified by chromatography on a silica gel column, eluting with chloroform:ether 100:5-100:4 to afford 160 mg of the title compound.
