Procedure

A mixture of 4-hydroxy-7-phenoxy-isoquinoline-3-carboxylic acid methyl ester (100 mg, 0.34 mmol) and 5-amino-valeric acid (597 mg, 5.1 mmol) in 0.5 N NaOMe in MeOH solution (6.8 mL, 3.4 mmol) was heated to reflux overnight. Reaction mixture was diluted with water (100 mL) and acidified by 1 N HCl solution to pH=3-4. Precipitate was collected and rinsed with water. It was dried in vacuo to provide the title compound (102 mg, 0.27 mmol) in 80% yield. LC-MS ESI−: 379.07 (M−1)−.
