실험 절차

Potassium carbonate (160 mg) and methanesulfonic acid cis-4-tert-butoxycarbonylaminocyclohexyl ester (140 mg, 0.47 mmol) were added to a solution of N-(6-mercaptoisoquinolin-1-yl)benzamide residue in DMA (4 ml). The mixture was irradiated in a microwave at 120° C. for 600 s then concentrated in vacuo to give a residue. The residue was purified by preparative HPLC to give trans-[4-(1-benzoylaminoisoquinolin-6-ylsulfanyl)cyclohexyl]carbamic acid tert-butyl ester. Glacial acetic acid (1 ml) and 6M hydrochloric acid (2 ml) were added to the trans-[4-(1-benzoylaminoisoquinolin-6-ylsulfanyl)cyclohexyl]carbamic acid tert-butyl ester and the mixture was refluxed for 24 h. The mixture was then concentrated in vacuo to give a residue. The residue was loaded onto a pre-acidified SCX column using methanol and then eluted with 2M ammonia in methanol to give cude trans-6-(4-aminocyclohexylsulfanyl)isoquinolin-1-ylamine, which was further purified using prep-HPLC (9 mg), EIMS: m/z=274.5 [M+H]+
