Reaction Steps

To a solution of 3-(2-chloropyrimidin-4-yl)-6-methyl-6-phenyl-1,3-oxazinan-2-one (50 mg, 0.165 mmol) and 4-fluorophenylboronic acid (32 mg, 0.33 mmol), K2CO3 (0.5 mL, 2 M) in 1,4-dioxane (1.5 ml) at 0° C. under N2 was slowly added Pd(Ph3)2Cl2 (10 mg, 20%). The mixture was refluxed overnight. The mixture was concentrated to give the crude product, which was purified by TLC and preparative HPLC to afford 3-(2-(4-fluorophenyl)pyrimidin-4-yl)-6-methyl-6-phenyl-1,3-oxazinan-2-one (15 mg, yield 25%). 1H NMR (CDCl3, 400 MHZ): δ=1.75 (s, 3H), 2.4 (m, 1H), 2.54 (m, 1H), 3.6 (m, 1H), 4.4 (m, 1H), 7.1 (m, 2H), 7.25-7.4 (m, 5H), 8.08 (m, 1H), 8.34 (m, 2H), 8.62 (m, 1H). LC-MS Method 3, tR=1.519 min, m/z=364.1. 1H NMR (CDCl3) 1.80 (s, 3H), 2.40 (m, 1H), 2.60-2.70 (d, 1H), 3.60 (m, 1H), 4.40 (t, 1H), 7.10 (t, 2H), 7.20-7.45 (m, 5H), 8.17 (d, 1H), 8.35 (t, 2H), 8.65 (d, 1H).
