Reaction Steps

To a solution of 6-allyl-3-(3-bromophenyl)-6-phenyl-1,3-oxazinan-2-one (50 mg, 0.134 mmol) and 2,4-difluorophenylboronic acid (40 mg, 0.215 mmol), K2CO3 (0.5 mL, 2 M) in 1,4-dioxane (1.5 ml) was slowly added Pd(Ph3)2Cl2 (10 mg, 20%) at 0° C. under N2. The mixture was refluxed overnight. The mixture was concentrated to give the crude product, which was purified by TLC and preparative HPLC to afford 6-allyl-3-(2′,4′-difluorobiphenyl-3-yl)-6-phenyl-1,3-oxazinan-2-one (10 mg, 18%). 1H NMR (400 MHz, CDCl3): δ=2.40 (m, 2H), 2.55-2.72 (m, 2H), 3.26 (m, 1H), 3.47 (m, 1H), 5.05 (m, 2H), 5.76 (m, 1H), 6.76-6.90 (m, 2H), 7.04 (m, 1H), 7.28 (m, 4H), 7.36 (m, 2H).
