A solution of trans-methyl[4-(1-oxo-1,2-dihydroisoquinolin-6-yloxy)cyclohexyl]-carbamic acid tert-butyl ester (400 mg, 1.07 mmol) in dichloromethane (9 ml) and trifluoroacetic acid (1 ml) was stirred at ambient temperature for 1 hour. The mixture was concentrated in vacuo then purified by ion exchange chromatography to give trans-6-(4-methylaminocyclohexyloxy)-2H-isoquinolin-1-one, EI-MS: m/z=273.4 [M+H]+.
