Procedure

EX-4A) 2-[3-Amino-2-oxo-2H-quinolin-1-yl]acetic acid, (0.206 g, 0.81 mmol) was treated with benzenesulfonyl chloride (0.172 g, 0.97 mmol) in pyridine for one hour. After removing the pyridine, the residue was recrystallized in acetone to yield a white crystal solid as the product, 2-[3-benzenesulfonylamino-2-oxo-2H-quinolin-1-yl]acetic acid, (EX-4A)(0.1 17 g, y=41% ). HPLC-MS (0 to 95% AcCN/6 min @ 1.0 mL/Min @ 254 nm @ 50° C.): retention time 2.85 min, M+H+=359.2 for formula C17H15N2O2S. 1H NMR (400 MHz, Acetone-d6): d 5.12 (s, 2H), 7.28 (t, J=7.2 Hz, 1H), 7.36 (d, J=8.8 Hz, 1H), 7.48-7.63 (m, 4H), 7.75 (dd, J=8, 1.6 Hz, 1H), 7.74 (s, 1H), 8.00-8.03 (m, 2H). 13C NMR (101 MHz, Acetone-d6): d (ppm) 44.8, 115.0, 120.8, 120.9, 123.9, 127.8, 128.1, 129.4, 129.9, 130.1, 134.2, 136.7, 140.4, 158.2, 169.1.
