Procedure
Potassium hydroxide (0.278 g) was added to a solution of 3-fluoro-4-nitrobenzoic acid (0.4 g) in ethanol (7 ml) and the reaction treated with microwaves (300W, 100° C.) for 55 minutes. The reaction mixture was acidified using 2N HCl and extracted with ethyl acetate. The extracts were combined, washed with water, dried (MgSO4) and evaporated to give 3-ethoxy-4-nitro-benzoic acid (0.325 g).
