Procedure

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. MS (DCI/NH3) m/z 404 (M+H)+. 1H NMR (CDCl3, 300 MHz) δ1.44 (s, 9H), 1.88 (m, 1H), 2.03 (m, 2H), 3.37 (m, 2H), 3.76 (m, 2H), 4.16 (m, 2H), 6.75 (m, 2H), 6.82 (m, 1H), 7.22 (m, 2H), 8.08 (m, 1H).
