Versuchsvorschrift

To a solution of [(R)-5-(5-amino-2-fluoro-phenyl)-6,6-difluoro-5-methyl-2,5,6,7-tetrahydro-[1,4]oxazepin-3-yl]-[bis-(4-methoxy-phenyl)-phenyl-methyl]-amine (intermediate A12A) (40 mg, 69.5 μmol) in toluene (0.6 ml) in a sealable tube was added subsequently at 23° C. and under an argon atmosphere 4-bromobenzonitrile (25.3 mg, 139 μmol), sodium tert-butoxide (13.4 mg, 139 μmol), 2-di-t-butylphosphino-2′,4′,6′-triisopropylbiphenyl (2.95 mg, 6.95 μmol) and tris(dibenzylideneacetone) dipalladium chloroform adduct (2.16 mg, 2.08 μmol), the tube was sealed and heated to 105 to 110° C. for 17 h. The mixture was cooled to 23° C., partitioned between saturated aqueous NaHCO3 and ethyl acetate, the organic layer was dried and evaporated to give the crude product, which was purified by silica gel flash chromatography with n-heptane/ethyl acetate and trituration with diethyl ether/pentane to give the (R)-4-(3-(3-(bis(4-methoxyphenyl)(phenyl)methylamino)-6,6-difluoro-5-methyl-2,5,6,7-tetrahydro-1,4-oxazepin-5-yl)-4-fluorophenylamino)benzonitrile (23 mg, 49%) as a light yellow crystalline. MS (ISN): m/z=675.5 [M−H]−.
