Participants

Reaction Steps

Sulphuric acid (83%, 20 ml) was cooled in an ice-bath, and 3-chloro-4-hydroxybenzoic acid (4 g, 22 mM) stirred in. After 10 minutes, nitric acid (70%, 1.43 ml, 22 mM) was run in, and the mixture stirred at 0° for 2 hours. After pouring onto ice, the solid was filtered, and recrystallised from aqueous ethanol to give title compound as yellow crystals (2.1 g, 44%).
