Reaction Steps

A suspension of 1-amino-6-hydroxyisoquinoline (0.08 g, 0.5mmol), methane-sulfonic acid trans-4-tert-butoxycarbonylaminocyclohexyl ester (176 mg) and 2-tert-butylimino-2-diethylamino-1,3-dimethyl-perhydro-1,3,2-diazaphosphorine on polystyrene (270mg, ˜2.2 mmol/g loading) in acetonitrile (2ml) were heated at 120° C. over a period of 15 minutes using the microwave. The excess supported reagent was removed by filtration, washing with acetonitrile followed by methanol, and the filtrate evaporated to dryness under reduced pressure. Purification was achieved by prep-HPLC to give cis-[4-(1-aminoisoquinolin-6-yloxy)cyclohexyl]carbamic acid tert-butyl ester (14 mg).
