In a dry tube under an atmosphere of argon to a solution of [bis-(4-methoxy-phenyl)-phenyl-methyl]-[(4R,5R)-4-(5-bromo-2-fluoro-phenyl)-5-fluoro-4-methyl-5,6-dihydro-4H-[1,3]oxazin-2-yl]-amine (intermediate C4.3) (250 mg, 412 μmol) and 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)nicotinonitrile (142 mg, 617 μmol) in 1,2-dimethoxyethane (3 ml) were added consecutively an aqueous solution of sodium carbonate (2M, 0.6 ml), triphenylphosphine (22.3 mg, 82.3 μmol), and, after flushing the mixture with argon, palladium(II)acetate (9.24 mg, 41.2 μmol). The tube was sealed and heated under stirring at 105° C. for 15 hours. After evaporation at reduced pressure, the residue was purified by chromatography on a silica-NH2 phase using a gradient of heptane/ethyl acetate=100:0 to 60:30 as the eluent. The 5-[3-((4R,5R)-2-{[bis-(4-methoxy-phenyl)-phenyl-methyl]-amino}-5-fluoro-4-methyl-5,6-dihydro-4H-[1,3]oxazin-4-yl)-4-fluoro-phenyl]-nicotinonitrile (260 mg, 100% yield) as a white foam. MS (ISP): m/z=631.4 [M+H]+.
