To a solution of 3-(2-chloropyrimidin-4-yl)-6-methyl-6-phenyl-1,3-oxazinan-2-one (100 mg, 0.33 mmol) and 3-fluorophenylboronic acid (80 mg, 0.53 mmol), K2CO3 (1 mL, 2 M) in 1,4-dioxane (3 ml) at 0° C. under N2 was slowly added Pd(Ph3)2Cl2 (20 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-(3-fluorophenyl)pyrimidin-4-yl)-6-methyl-6-phenyl-1,3-oxazinan-2-one (20 mg, yield 17%). 1H NMR (CDCl3, 400 MHZ): δ=1.71 (s, 3H), 2.37 (m, 1H), 2.6 (m, 1H), 3.54 (m, 1H), 4.34 (m, 1H), 7.08 (m, 1H), 7.25 (m, 1H), 7.34 (m, 5H), 7.96 (m, 1H), 8.09 (m, 1H), 8.16 (m, 1H), 8.6 (m, 1H). LC-MS Method 3, tR=1.46 min, m/z=364.
