実験手順

A dried pressure tube was consecutively charged with [bis-(4-methoxy-phenyl)-phenyl-methyl]-{(R)-5-[5-(5,5-dimethyl-[1,3,2]dioxaborinan-2-yl)-2-fluoro-phenyl]-6,6-difluoro-5,7,7-trimethyl-2,5,6,7-tetrahydro-[1,4]oxazepin-3-yl}-amine (intermediate B10.1) (100 mg, 127 μmol), tetrahydrofuran (3 ml), 2,6-dichlorobenzo[d]oxazole (31.6 mg, 165 μmol), cesium carbonate (165 mg, 507 μmol) and water (1.5 ml). The tube was flushed with argon, thereafter [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) dichloromethane complex (11 mg, 12.7 μmol) was added, the tube was sealed and the reaction mixture heated at 85° C. for 64 hours. For the workup, the reaction mixture was evaporated at reduced pressure and the residue directly purified by chromatography on silica gel using a gradient of heptane/ethyl acetate=100:0 to 80:20 as the eluent. The [bis-(4-methoxy-phenyl)-phenyl-methyl]-{(R)-5-[5-(6-chloro-benzo oxazol-2-yl)-2-fluoro-phenyl]-6,6-difluoro-5,7,7-trimethyl-2,5,6,7-tetrahydro-[1,4]oxazepin-3-yl}-amine (41 mg, 44% yield) was obtained as a white solid. MS (ISP): m/z=740.4 [M+H]+ and 742.3 [M+2+H]+.
