Procedure
Tetrakis(triphenylphosphine)palladium(0) (3.3 mg) was added to a solution of (S)-6-(cyclopropylmethyl)-6-(2-hydroxy-2-methylpropyl)-3-{(S)-1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]ethyl}-1,3-oxazinan-2-one (150 mg), 1-(5-bromopyridin-2-yl)cyclopropanecarboxamide (94 mg), and Na2CO3 (348 mg, 3.28 mmol) in ethanol (8 mL), toluene (12 mL), and H2O (4 mL) at room temperature. The reaction mixture was heated to 100° C. for 2 h. After cooling to room temperature, the formed mixture was concentrated to afford an oil which was diluted with H2O (30 mL) and extracted with ethyl acetate (3×50 mL). The combined organic layer was concentrated to afford an oil which was purified by preparative TLC and preparative HPLC to give the title compound. Yield: 30 mg (19% of theory); LC (method 4): tR=0.95 min, Mass spectrum (ESI+): m/z=492 [M+H]+; 1H NMR (CDCl3, 400 MHz) δ 0.01 (d, 2H), 0.40-0.50 (m, 2H), 0.69 (m, 1H), 1.27 (m, 2H), 1.33 (s, 3H), 1.39 (s, 3H), 1.61 (d, 3H), 1.78 (m, 1H), 1.82 (m, 2H), 1.89-2.05 (m, 4H), 2.21 (m, 1H), 2.80 (m, 1H), 3.19 (m, 1H), 5.51 (1H), 5.85 (m, 1H), 7.29 (m, 1H), 7.48 (d, 2H), 7.58 (d, 2H), 7.82 (1H), 7.89 (d, 1H), 8.79 (s, 1H).
