Reaction Steps
A suspension of 2.6 g of (3,4-dihydroxy-5-nitrobenzoyl)methyl acetate in 20 ml of ethanol and 20 ml of 1N hydrochloric acid is heated to boiling under reflux for 5 hours. The reaction mixture is then evaporated, the residue is distilled with toluene and then recrystallized from ethanol. There is obtained 2,3',4'-trihydroxy-5'-nitroacetophenone of m.p. 208°-210°.
