The reaction of 4-aminobenzophenone (I) with benzylmagnesium bromide (II) in ether gives the carbinol (III), which by reaction with acetic anhydride in hot pyridine yields the olefinic acetamide (IV). The chlorination of (IV) with Cl2 in CCl4 followed by refluxing in the same solvent affords the chlorovinyl acetamide (V), which is alkylated at the amidic nitrogen with 2-chloroethyl(diethyl)amine (VI) by means of KOH in refluxing acetone giving the disubstituted acetamide (VII). Finally, the deacetylation of (VII) with hot 10% HCl and salification with citric acid affords the target compound.
