実験手順
A mixture of 2-chloro-5-(isoquinolin-6-yl)oxazole 14 (0.15 g, 0.652 mmol) and commercially available N-(3-aminophenyl)methanesulfonamide 6 (0.121 g, 0.649 mmol) in 2-propanol (20 mL) was heated to 80° C. for 12 h with stirring. Additional one more equivalent of N-(3-aminophenyl)methanesulfonamide 6 (0.121 g, 0.649 mmol) was added to reaction mixture and heated to 80° C. for further 12 h with stirring. Upon cooling, solvent was evaporated and silica column purified (Biotage) (Acetone/hexane as an eluent) to provide N-(3-((5-(isoquinolin-6-yl)oxazol-2-yl)amino)phenyl)methane sulfonamide 59 (0.09 g, 38% yield) as pale yellow solid. MS (ES) m/z 381 (M+H+).
