실험 절차
Trifluoroacetic acid (1 ml) was added to a suspension of {1-[8-(3-Sulfamoyl-phenylamino)-thiazolo[4,5-h]quinazoline-2-carbonyl]-pyrrolidin-3-yl}-carbamic acid tert-butyl ester (87 mg, 0.15 mmol) in dichloromethane (1 ml). The reaction mixture was stirred at room temperature for 1 hour. The solution was concentrated under reduced pressure and the residue was purified by reverse phase preparative HPLC [Waters Delta-Pak C18, 15 uM, 100 A column, gradient 10%-100% B (solvent A: 0.05% TFA in water; solvent B: CH3CN) over 10 minutes at 25 mL/min] to afford the title compound as a yellow solid. MS (ES+) 470, (ES−) 468. δH (d6 DMSO) 2.0-2.5 (4H, m), 3.70-4.05 (3H, m), 4.31-4.44 (2H, m), 7.37 (2H, s), 7.52 (1H, d), 7.60 (1H, t), 8.02-8.13 (6H, m), 8.69 (1H, s), 9.55 (1H, d), 10.57 (1H, s).
