Reaction Steps
Dilute sodium hydroxide solution was added to a suspension of 4-hydroxy-6-methoxy-3-nitrocoumarin (2.0g) in water (40 ml) till the pH of the solution reached 14. Filtration gave the product m.p. 277°-8°(d); (C10H6NO6Na requires C, 46.35; H, 2.33; N, 5.41; Na, 8.87. Found: C, 46.32; H, 2.44; N, 5.50; Na, 8.34) after washing briefly with water and drying under vacuum.
