실험 절차

A mixture of [(1-chloro-4-methoxy-isoquinoline-3-carbonyl)-amino]-acetic acid methyl ester (21 mg, 0.07 mmol), KOH (23 mg, 0.35 mmol) and EtOH (1 ml) was stirred at ambient temperature for 3 h. Then the solvent was evaporated in vacuo. The residue was dissolved in water (2 ml) and the pH of the solution was adjusted to 2-3 by the addition of aqueous 1N HCl. The mixture was extracted with EtOAc (4×10 ml). The combined org. phases were dried over MgSO4 and evaporated in vacuo to give the title compound as a slightly yellowish solid (18 mg); MS-(+)-ion: M+1=295.0.
