Procedure

Pd(PPh3)4 (1 mg) was added to a mixture of 1-(5-bromopyrimidin-2-yl)imidazolidin-2-one (13 mg), (S)-6-(2-hydroxy-2-methylpropyl)-6-phenyl-3-{(S)-1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxa-borolan-2-yl)phenyl]ethyl}-1,3-oxazinan-2-one (38.6 mg) and Na2CO3 (17 mg) in toluene (3 mL), ethanol (2 mL), and H2O (1 mL) at room temperature. The reaction mixture was heated to 100° C. under nitrogen and stirred at this temperature for 2 h. After cooling to room temperature, the mixture was concentrated to give an oil, which was purified by preparative HPLC to afford the title compound. Yield: 3.1 mg (11% of theory); LC (method 4): tR=0.93 min; Mass spectrum (ESI+): m/z=516 [M+H]+; 1H NMR (CD3OD) δ 0.92 (s, 3H), 1.32 (s, 3H), 1.58 (d, 3H), 2.06 (s, 2H), 2.19 (m, 2H), 2.50 (m, 2H), 3.58 (m, 2H), 4.20 (m, 2H), 5.62 (m, 1H), 7.11 (d, 2H), 7.33 (m, 5H), 7.42 (d, 2H), 8.78 (m, 2H).
