4-Chloro-alpha-methylbenzhydrol (I) is alkylated with N-(2-chloroethyl)hexamethyleneimine (II) in benzene in the presence of sodium amide to give setastine. The starting products are obtained as follows; Caprolactame (III) is O-alkylated with dimethyl sulfate to yield the lactimether (IV), which is reduced with sodium borohydride to hexamethyleneimine (II). Friedel Cratts acylation of chlorobenzene (V) with benzoyl chloride (VI) affords the benzophenone (VII), to which methylmagnesium bromide is added to give the carbinol (I).
