실험 절차

A mixture of 6-chloro-2-ethyl-1-(4-{2-[({[(4-methylphenyl)sulfonyl]amino}carbonyl)amino]ethyl}phenyl)-1H-benzimidazole-5-carboxamide (Example 111, 140 mg, 0.26 mmol) and KOH (63 mg, 0.8 mmol) in methanol (10 mL) was stirred at 100° C. for 1 day. The mixture was poured into water, acidified with 2N hydrochloric acid, and extracted with ethyl acetate (50 mL). The organic layer was washed with brine (30 mL), dried (Na2SO4), and concentrated. The residue was purified by flash column chromatography on silica gel eluting with dichloromethane/methanol (10:1) to afford 36 mg (25%) of the title compound as white solids: mp 145-150° C.; MS (ESI) m/z 541 (M+H)+; 1H-NMR (DMSO-d6) δ 8.10 (1H, s), 7.76 (2H, d, J=7.9 Hz), 7.36-7.47 (6H, m), 7.10 (1H, s) 3.28 (2H, m), 2.69-2.81 (4H, m), 2.34 (3H, s), 1.24 (3H, t, J=7.5 Hz); IR (KBr) αmax : 3450, 1701, 1517, 1340, 1163, 1091, 900 cm−1.
