Embodiment 1
[0056] Example 1 Preparation of hydrochloric acid addition salt of [(4-hydroxyl-1-methyl-7-phenoxy-isoquinoline-3-carbonyl)amino]-acetic acid (formula Ⅰ)
[0057] 1 g of [(4-hydroxy-1-methyl-7-phenoxy-isoquinoline-3-carbonyl)amino]-acetic acid was dissolved in 10 mL of dichloromethane and stirred at room temperature. 0.11 g of hydrochloric acid was added dropwise to the reaction solution. After stirring the reaction solution at room temperature for 1 h, the reaction solution was evaporated to dryness, washed with n-hexane and dried in vacuo. Thus, 0.98 g of white solid was obtained, yield 89.3%. ESI-MS (M+H, 354.5), elemental analysis: C 58.69%, H 4.41%, N 7.21%, O2 0.58%, Cl 9.12%.
[0058] 1 H-NMR (DMSO) δ: 3.14 (s, 3H), 3.60 (d, 2H), 5.35 (s, -OH), 7.25 (s, 1H), 7.29 (s, 1H), 7.14 (s, 2H) , 7.41 (s, 2H), 7.17 (s, 1H), 8.03 (t, 1H), 8.09 (s, 1H).

[0062] Example 2 Preparation of [(4-hydroxyl-1-methyl-7-phenoxy-isoquinoline-3-carbonyl)amino]-acetic acid (formula Ⅰ) sodium salt
[0063] Dissolve 1 g of [(4-hydroxy-1-methyl-7-phenoxy-isoquinoline-3-carbonyl) amino]-acetic acid in 10 mL of dichloromethane, add 1.1 equivalents of 10% aqueous sodium hydroxide to in the reaction solution. After stirring the reaction solution at room temperature for 1 h, the dichloromethane reaction solution was evaporated to dryness, washed with n-hexane and dried in vacuo. Obtained 0.99 g of white solid, yield 92.8%. ESI-MS (M-H, 352.5), elemental analysis: C 60.96%, H 4.04%, N 7.48%, Na 6.14%, O 21.37%.
[0064] 1 H-NMR (DMSO) δ: 3.14 (s, 3H), 4.21 (d, 2H), 5.35 (s, -OH), 7.25 (s, 1H), 7.29 (s, 1H), 7.14 (s, 2H) , 7.41 (s, 2H), 7.17 (s, 1H), 8.03 (t, 1H), 8.09 (s, 1H).
