Versuchsvorschrift

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 triethylamnine (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) δ1.08 (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).
