実験手順

4-Chloro-1-guanidino-N-{1-[(4-methylpiperazino)carbonyl]cyclopentyl}-7-isoquinolinesulphonamide dihydrochloride ##STR90## Triethylamine (1.36 ml, 10.0 mmol) was added to a solution of (1-aminocyclopentyl)(4-methyl-1-piperazinyl)methanone dihydrochloride (567 mg, 2.0 mmol) and 1,4-dichloro-7-isoquinolinesulphonyl chloride (592 mg, 2.0 mmol) in CH2Cl2 (25 ml), and the reaction stirred at room temperature for 18 h. The mixture was concentrated in vacuo and the residue partitioned between EtOAc and water, and the layers separated. The organic phase was washed with water, extracted with HCl (2N), and these combined acidic extracts washed with EtOAc, and re-basified using Na2CO3. This aqueous solution was extracted with EtOAc, the combined organic extracts washed with brine, dried (Na2SO4) and evaporated in vacuo to give a foam. This was crystallised from CH2Cl2 -i-Pr2O to afford 1,4-dichloro-N-{1-[(4-methyl-1-piperazinyl)carbonyl]cyclopentyl}-7-isoquinolinesulphonamide (153 mg, 0.33 mmol) as a solid.
