    摘要: The invention relates to a novel process for the preparation of 2-[2-(4-fluorophenyl)-2-oxo-1-phenylethyl]-4-methyl-3-oxo-pentanoic acid phenylamide and to novel intermediates and process steps therefor. In that process inter alia the intermediate 2-[2-(4-fluorophenyl)-2-oxo-1-phenylethyl]-4-methyl-3-oxo-pentanoic acid phenylamide is obtained by nucleophilic substitution from a compound of formula (I), wherein X is a nucleofugal leaving group, with a ketoamide of formula (II) in the presence of a base.
