Dibenzyl [(E)-{1-[1-(4-fluorophenyl)cyclobutyl]-7-{2-[(propylsulfonyl)amino]ethoxy}-3,4-dihydroisoquinolin-2(1H)-yl}methylylidene]biscarbamate (95 mg, 0.126 mmol) was dissolved in methanol (8 mL) under an atmosphere of nitrogen. Acetic acid (0.4 mL) was added followed by 10% palladium on charcoal (40 mg, 0.038 mmol). The nitrogen was replaced by one atmosphere of hydrogen and the reaction mixture was stirred at room temperature for 3 h. The catalyst was removed by filtration and the solution of the product was concentrated in vacuo. The product was dissolved in ethanol (0.5 mL) and water (15 mL) and was lyophilized. Yield: 61 mg (0.125 mmol, 99%).
