実験手順

In analogy to the procedure described for the synthesis of 2-(3,4-Dichloro-phenyl)-4-oxo-butyric acid methyl ester (example 2, step 1) the title compounds was prepared from 4-fluoro-phenyl-acetic acid methyl ester (commercially available), and bromoacetaldehyde dimethylacetal and subsequent treatment with HCl aq. MS (m/e): 209.3 (MH−).
