Versuchsvorschrift

The product from Example 68A (6.5 g, 18.5 mmol) was sequentially treated with a 0.1M solution of the product from Example 68B in acetonitrile (230 mL, 23.0 mmol), Pd(OAc)2 (0.127 g, 0.566 mmol), tris(4-methylphenyl)phosphine (0.344 g, 1.130 mmol), and copper iodide (1.08 g, 95.72 mmol). After stirring at 25° C. for 10 minutes, the reaction mixture was treated with diisopropyl amine (26.6 mL, 189 mmol) and then heated at 60° C. in an inert atmosphere for 16 hours. The reaction mixture was allowed to cool to room temperature, filtered through celite, and the filtrate concentrated under reduced pressure. The residue was purified on silica gel using 90% DCM, 9.9% MeOH, 0.1% NH4OH to provide the title compound (1.21 g, 18.0% yield). 1HNMR (300 MHz, CD3OD) δ 1.09 (d, 3H, J=6.1 Hz), 1.46 (m, 1H), 1.81 (m, 2H), 2.02-2.28 (m, 2H), 2.49 (m, 2H) 3.06 (m, 2H), 3.28 (m, 2H), 6.68 (s, 1H),), 7.27 (t, 2H), 7.58 (d, 1H, J=8.9 Hz), 7.71 (d, 1H, J=8.9 Hz) 7.86 (t, 2H), 7.97 (s, 1H); MS (ESI) m/z 352 (M+H)+.
