Reaction Steps
9.8 g of potassium tert.butylate were dissolved in 90 ml of DMF and cooled to −45° C. For this purpose, a mix of ethyl 2-chloro-2-phenylacetate (43.8 mmol, 8.7 g) and 1-fluoro-2-nitrobenzene (43.8 mmol, 4.6 ml) was carefully added dropwise and the mixture was stirred for a further 20 minutes. The reaction mix was set to pH 4 using 16% HCl, diluted with 25 ml of water and extracted with EtOAc (3×50 ml). Once combined, the organic phases were washed with water and sat. aq. NaCl sol., dried over MgSO4 and concentrated under vacuum. The resulting residue was purified by column chromatography (silica gel: mesh 100-200, eluent: 10% EtOAc in cyclohexane) and produced 5.9 g (44.9%) of product.
