N,N-Dimethylformamide (5 mL) was added to a flask charged with a stir bar, 3-[(S)-1-(4-bromo-phenyl)-ethyl]-(S)-6-(2-hydroxy-2-methyl-propyl)-6-phenyl-[1,3]oxazinan-2-one (0.30 g), 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (0.22 g), K2CO3 (0.29 g), and [1,1′-bis(diphenylphosphino)-ferrocene]-dichloropalladium(II) (57 mg) under argon atmosphere. The resulting mixture was stirred at 80° C. overnight. After cooling to ambient temperature, water was added and the resulting mixture was extracted with ethyl acetate. The combined organic extracts were washed with brine, dried (MgSO4), and concentrated. The residue was purified by chromatography on silica gel (cyclohexane/ethyl acetate 40:60→0:100) to afford the title compound.
