Procedure
2-(4-Fluoro-phenoxy)-5-nitro-benzoic acid can be prepared by a similar method to that described in the literature (e.g. WO9938845) by reaction of 2-Chloro-5-nitro-benzoic acid ethyl ester [16588-17-3] with 4-Fluoro-phenol [371-35-7] yielding 2-(4-Fluoro-phenoxy)-5-nitro-benzoic acid ethyl ester. 2-(4-Fluoro-phenoxy)-5-nitro-benzoic acid ethyl ester can then be hydrolysed with sodium hydroxide for example to yield the title compound. MS (m/e): 276.1 (M+H+, 100%).
