실험 절차

To a solution of 2-chloro-4-isopropyl-benzoic acid (63 mg, 0.33 mmol) in DMF (4 mL) was added HATU (90 mg, 0.23 mmol) and DIEA (43 mg, 0.33 mmol). After 1 hour 6-amino-3,3-dimethyl-3H-benzo[c][1,2]oxaborol-1-ol hydrochloride salt (50 mg, 0.22 mmol) was added. After 12 hours the reaction was concentrated down under reduced pressure onto celite. The crude material was subjected to flash chromatography (Isco Companion, 4 g SiO2 cartridge, SiO2 solid load, neat DCM to 10% MeOH gradient) to give 2-Chloro-N-(1-hydroxy-3,3-dimethyl-1,3-dihydro-benzo[c][1,2]oxaborol-6-yl)-4-isopropyl-benzamide as a white powder. Amount obtained: 6.3 mg (8%). Data: LCMS (M/Z): 358 (M+H); 1H NMR (DMSO-d6) δ: 1.23 (d, J=6.8 Hz, 6 H) 1.44 (s, 6 H) 2.97 (dt, J=13.8, 6.9 Hz, 1 H) 7.29-7.41 (m, 2H) 7.43 (d, J=1.4 Hz, 1 H) 7.49 (d, J=7.8 Hz, 1 H) 7.68 (dd, J=8.3, 1.9 Hz, 1 H) 8.05 (dd, J=1.7, 0.5 Hz, 1 H) 9.08 (br. s, 1 H) 10.45 (s, 1 H).
