Participants

Reaction Steps

tert-Butyl 3-{[(4-chloro-1-guanidino-7-isoquinolinyl)sulphonyl]amino}benzoate (30 mg, 0.063 mmol) was dissolved in CF3CO2H (1.0 mL) and the mixture stirred at room temperature for 1 h. The mixture was diluted with PhMe and the solvents were evaporated in vacuo. The residue was triturated with Et2O and then azeotroped with CH2Cl2 to give 3-{[(4-chloro-1-guanidino-7-isoquinolinyl)sulphonyl]amino}-benzoic acid trifluoroacetate (29 mg, 0.055 mmol) as an off-white solid.
