Reaction Steps

To a solution of 5-bromo-6-chloro-3-(1-BOC-2-(R)-pyrrolidinylmethoxy)pyridine from Example 69a (460 mg, 1.2 mmol) and 4-chlorophenylboronic acid (225 mg, 1.44 mmol) in toluene (10 mL) was added Pd(0) (40 mg) and Na2CO3 (1.2 mL of a 2 M solution), and the mixture was heated at reflux for 1.5 hours. The solvent was removed under vacuum, and the residue was purified by chromatography on a silica gel column, eluting with hexane:Et2O 100:10-100:30 to afford of the title compound (345 mg, 68% yield). MS (CI/NH3) m/z 423 (M+H)+. 1H NMR (CDCl3, 300 MHz) δ1.45 (s, 9H), 1.89 (m, 2H), 2.03 (m, 2H), 3.37 (m, 2H), 4.00 (m, 1H), 4.15 (m, 2H), 7.42 (m, 6H), 8.10 (m, 2H).
