실험 절차
Ethyl 2-(5-fluoro-2-(6-(N-(4-methoxybenzyl)-N-(thiazol-2-yl)sulfamoyl)isoquinolin-1-yl)phenoxy)acetate was dissolved in methanolic ammonia and heated at 60° C. for 16 h in a sealed tube. The reaction mixture was concentrated to obtain 2-(5-fluoro-2-(6-(N-(4-methoxybenzyl)-N-(thiazol-2-yl)sulfamoyl)isoquinolin-1-yl)phenoxy)acetamide as light yellow solid. m/z (ESI) 579.2 (M+H)+. This was then dissolved in DCM (1 mL) and 4 drops of TFA were added and the reaction was stirred for 15 min. The reaction mixture was loaded on 10 g silica gel column and eluted with DCM:MeOH (90:10) up to 100% to obtain 2-(5-fluoro-2-(6-(N-(thiazol-2-yl)sulfamoyl)isoquinolin-1-yl)phenoxy)acetamide (3.9 mg, 8.51 μmol, 2.96% yield) as light yellow solid. m/z (ESI) 459.0 (M+H)+.
