Reaction Steps

A solution of 5-bromo-6-chloro-3-(1-BOC-2-(R)-pyrrolidinylmethoxy)pyridine from Example 69a (480 mg, 1.2 mmol), 5-(5,5-dimethyl-1,3-hexadiene (200 mg, 1.8 mmol), Pd(OAc)4 (25 mg), tris(o-tolyl)phosphine (125 mg), and triethylamine (2.5 mL) in acetonitrile (5 mL) was sealed in a tube and headed at 100° C. for 4 days. The solution was then diluted with EtOAc, and the mixture was extracted 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:Et2O 100:5-100:15 to afford the title compound (135 mg, 43% yield). MS (CI/NH3) m/z 421 (M+H)+. 1H NMR (CDCl3, 300 MHz) δ 1.08 (s, 9H), 1.48 (s, 9H), 1.89 (m, 2H), 2.00 (m, 2H), 3.38 (m, 2H), 3.95 (m, 1H), 4.13 (m, 1H), 4.23 (m, 1H), 5.99 (m, 1H), 6.22 (m, 1H), 6.71 (m, 1H), 6.95 (m, 1H), 7.74 (br s, 1H).
