Procedure
To a solution of (2S)-2-(4-chloro-2-hydroxyphenoxy)-propanoic acid (0.216 g) and 1-fluoro-4-nitro-benzene (0.127 g) in NUT (3 ml) was added potassium carbonate (0.276 g) and the reaction heated at 90° C. for 2 h. After cooling to RT, water and diethylether were added. The aqueous layer was separated and extracted again with diethylether. The aqueous layer was isolated, acidified to pH 2 and extracted with diethylether. This later extract was dried and evaporated under reduced pressure. The residue was purified by chromatography on silica eluting with 30-50% ethylactate/isohexane+1% AcOH, yield 0.2 g
