with sodium hydroxide in ethanol;water at 60; for 5 h;
Steps:
5 Example 5 Production of 7-bromo-1,5-naphthyridine-3-carboxylic acid
Methyl 7-bromo-1,5-naphthyridine-3-carboxylate (26 g, 98 mmol) was dissolved in ethanol (150 mL)Add 10% NaOH aqueous solution (260 mL), add the reaction solution to 60 ° C for 5 h, and evaporate to remove ethanol.Adjust the pH to 4-6 with 2M hydrochloric acid, precipitate a solid, and filter with suction.Drying gave the desired product 7-bromo-1,5-naphthyridin-3-carboxylic acid (25 g, white solid, yield 99%).
