Trifluoroacetic acid (1 ml) and dichloromethane (5 ml) were added to 3-(1-chloro-isoquinolin-6-yloxy)piperidine-1-carboxylic acid tert-butyl ester (370 mg) and the mixture stirred at ambient temperature for 48 h. The mixture was concentrated in vacuo then loaded onto a pre-acidified SCX column using methanol and eluted with 2M ammonia in methanol to afford 1-chloro-6-(piperidin-3-yloxy)isoquinoline (180 mg).
