Versuchsvorschrift

To a mixture of [(1-cyano-4-methoxy-8-phenoxy-isoquinoline-3-carbonyl)-amino]-acetic acid methyl ester (21 mg, 0.05 mmol), and methanol/tetrahydrofuran (0.9 mL, 1:3.5) was added 2N sodium hydroxide (29.2 μL, 0.06 mmol) at room temperature. The yellow solution was stirred at that temperature for fifty-five minutes before it was acidified with 1N HCl (69.1 μL) to pH=3 and concentrated in vacuo. The residue was partitioned between ethyl acetate and water. The organic layer was dried over anhydrous sodium sulfate, concentrated in vacuo and the residue was purified by flash column chromatography on silica gel with a gradient of methanol, dichloromethane and acetic acid (0.1%) to give the title compound as a pale brown solid (15 mg): MS: (+) m/z 378.00 (M+1).
