Versuchsvorschrift
A mixture of 1-cyano-4-hydroxy-6-(4-propoxy-phenoxy)-isoquinoline-3-carboxylic acid butyl ester (200 mg, 0.422 mmol), glycine (633 mg, 8.43 mmol) and NaOMe/MeOH solution (12.7 mL, 6.33 mmol) was refluxed overnight. Then the mixture was concentrated in vacuo and the residue was dissolved in water. The solution was acidified with 2 M HCl to pH=3˜4. The resulting precipitate was collected by filtration, washed with water, and freeze-dried to give the title compound as a powder (209 mg); ESI MS (m/z): 422 (M+H)+.
