The title compound was prepared starting from 5.00 g (28.57 mmol) of 4-bromofluorobenzene and 4.86 g (31.43 mmol) of 4-chloroacetophenone in analogy to the synthesis of the compound from Example 176A. A difference was that a preliminary separation by column chromatography on silica gel (mobile phase: cyclohexane/ethyl acetate 9/1) was carried out before the purification of the crude product by preparative HPLC. 5.23 g (73% of theory) of the title compound were obtained.
