実験手順

To the mixture of 2-(5-amino-2-(N-(1-hydroxy-1,3-dihydrobenzo[c][1,2]oxaborol-6-yl)sulfamoyl)phenyl)acetic acid (1.09 g, 3 mmol) and cyclohexyl amine (1.4 ml, 12 mmol) in DMF (10 ml), added PyBOP (1.56 g, 3 mmol) then triethyl amine (0.4 ml, 3 mmol). Stirring was kept for 3 hours. Diluted with EtOAc, washed with 1N HCl, water and brine. Dried over anhydrous sodium sulfate. Concentrated, the residue was dissolved in DMSO and purified by prep HPLC (SunFire Prep C18 OBD 5 uM 30×50 mm column). The title compound was obtained as light yellow powder. MS calcd for (C21H26BN3O5S): 443.17. MS found (ESI negative): (M−H)−=442.2. 1H NMR (400 MHz, DMSO-d6) δ (ppm): 9.87 (s, 1H), 7.90 (d, J=6 Hz, 1H), 7.41 (s, 1H), 7.39 (d, J=8.8 Hz, 1H), 7.20 (d, J=8 Hz, 1H), 7.08 (dd, J=8 Hz, 1H), 6.45 (d, J=2 Hz, 1H), 6.33 (dd, J=8.8 Hz, 1H), 4.85 (s, 2H), 3.75 (s, 2H), 3.55 (m, 1H), 1.80-1.50 (m, 5H), 1.30-1.10 (m, 5H).
