Participants

Reaction Steps

A solution of 5-chloro-2,4-dinitrobenzamide (5.50 g, 0.022 mmol) in p-dioxane/methanol (1:1, 120 mL) and 6N aqueous KOH (20 mL) is stirred at room temperature for 2 h. After acidification with concentrated HCl, the mixture is diluted with water and extracted into EtOAc. Workup gives 2,4-dinitro-5-hydroxybenzamide (4.91 g, 98%) as yellow cubes. 1H NMR (DMSO) δ8.64 (1H, s), 8.16 (1H, brs), 7.81 (1H, brs), 7.13 (1H, s), 5.80 (1H, brs).
