Procedure: Argon was bobbled through a mixture of N-(2-Iodo-benzyloxy)-2-[(pyridin-4-ylmethyl)-amino]-benzamide (example 360, 151 mg, 0.33 mmol) in toluene (20 ml) for 10 to 15 minutes. Tetrakis(triphenylphosphine) palladium (19 mg) was added and the mixture was stirred for 10 minutes before addition of 3,3-dimethyl-1-butenylboronic acid (Aldrich, 50 mg) and a degassed 2M solution of sodium carbonate (0.329 ml). The reaction flask (screw-cap) was sealed and the reaction mixture was heated to 120° C. for 3 hours. More tetrakis(triphenylphosphine) palladium (0.05 eq.), 2M sodium carbonate (0.329 ml), and 3,3-dimethyl-1-butenylboronic acid (50 mg) was added and stirring was continued at 120° C. over night. The mixture was cooled to room temperature and 25% ammonium acetate was added and stirring was continued for 10 min. The mixture was partitioned between EtOAc and water. The aqueous phase was extracted with EtOAc and the combined organic layers were washed with brine, dried (MgSO4) and evaporated under reduced pressure. The residue was subjected to chromatography on silica gel (elution with 1% methanol in dichloromethane v/v) and gave the title compound (130 mg). 13C-NMR (CDCl3) δ 168.9, 149.8, 149.1, 148.7, 145.1, 138.8, 133.4, 131.1, 129.2, 127.4, 126.8, 126.2, 122.0, 121.5, 115.7, 112.8, 112.0, 76.2, 46.1, 33.8, 29.6.
