PROCEDURE
实验过程
To a solution of methyl (2S)-2-[(benzyloxy)carbonyl]amino-3-[3-bromo-4-(1,1-dioxido-3-oxoisothiazolidin-5-yl)phenyl]propanoate (52.0 mg, 0.0990 mmol) in toluene (1.0 mL) and 1,4-dioxane (1.0 mL) was added phenylboronic acid (14.5 mg, 0.119 mmol), 2 M sodium carbonate in water (0.30 mL) and tetrakis(triphenylphosphine)palladium(0) (6 mg, 0.005 mmol) under an atmosphere of nitrogen. The resulting mixture was heated at 100° C. overnight. The reaction solution was filtered, and purified by preparative LCMS to afford product as a white solid (18 mg, 38%). 1H NMR (400 MHz, CD3OD): δ 7.28 (m, 13H), 5.03 (m, 1H), 4.47 (m, 1H), 3.26 (m, 3H), 3.00 (m, 1H). LCMS found for C26H25N2O7S (M+H)+: m/z=509.
