実験手順

[(1-Cyano-4,7-dihydroxy-isoquinoline-3-carbonyl)-amino]-acetic acid was prepared by heating a mixture of 42 mg (0.162 mmol) of 1-Cyano-4,7 dihydroxy-isoquinoline-3-carboxylic acid ethyl ester and 97 mg (1.29 mmol) of glycine in 2.25 mL of 0.5 N NaOMe in methanol at reflux temperature for 26 hours. The reaction mixture was cooled and acidified with 3 mL of 1 N HCl and water. A white solid was collected on a medium glass fritted filter to provide 40 mg of the title compound; MS (ESI+): 288.2 e/z (M+1)
