실험 절차

A mixture of 5-bromo-6-chloro-3-(1BOC-2-(R)-pyrrolidinylmethoxy)pyridine from Example 69a (425 mg, 1.1 mmol), 1-octyne (0.2 mL, 1.4 mmol), Pd(PPh)3Cl2 (20 mg), CuI (catalytic amount) and triethylamine (0.5 mL) in methylene chloride (8 mL) was heated at reflux for 16 hours. Heating was continued until no starting material remained. The solvent was removed, and the residue was washed with 10% NaOH then extracted with methylene chloride. The organic extract was dried over MgSO4 and concentrated. The residue was chromatographed on a silica gel column, eluting with hexane:ether 100:6-100:15 to afford to give the title compound (335 mg, 72% yield). MS (DCI/NH3) m/z 421 (M+H)+. 1H NMR (CDCl3, 300 MHz) δ0.90 (m, 3H), 1.32 (m, 4H), 1.48 (s, 9H), 1.49 (m, 2H), 1.62 (m, 2H), 1.88 (m, 2H), 2.00 (m, 2H), 2.48 (m, 2H), 3.34 (m, 2H), 3.90 (m, 1H), 4.12 (m, 2H), 7.30 (br s, 1H), 7.98 (m, 1H).
