Reaction Steps

A mixture of 5-bromo-3-(1-BOC-2-(R)-pyrrolidinylmethoxy)pyridine (440 mg, 1.25 mmol), 4-vinylpyridine (0.267 mL), Pd(OAc)4 (30 mg), tris(o-tolyl)phosphine (160 mg), and triethylamine (3.5 mL) in acetonitrile (4 mL) was heated at reflux for 16 hours. The solution was then concentrated, and the residue was washed with water and aqueous NaHCO3 solution. The organic layer was dried and concentrated. The residue was chromatographed on a silica gel column, eluting with hexane:ethyl acetate 1:3 to afford the title compound (440 mg, 79% yield). MS (DCI/NH3) m/z 382 (M+H)+. 1H NMR (CDCl3, 300 MHz) δ: 1.49 (s, 3H), 1.85-2.12 (m, 4H), 3/26-3.55 (m, 2H), 3.86-4.08 (m, 1H), 4.08-4.34 (m, 1H), 7.20-7.30 (m, 2H), 7.36-7.42 (m, 2H), 7.71 (br s, 0.5H), 8.22-8.42 (m, 1.5H), 8.58-8.69 (m, 2H).
