Reaction Steps

2-Hydroxy-5-methyl-3-nitrobenzoic acid (10.0 g) was dissolved in absolute ethanol (50 ml) and the solution was treated with concentrated sulphuric acid (3.0 ml), slowly with stirring. The mixture was heated at reflux for 20 hours and then poured into water (250 ml). The resulting yellow solid was recrystallised from ethanol to give ethyl 2-hydroxy-5-methyl-3-nitrobenzoate (7.5 g), m.p. 97° C.
