1) Alkylation of diethyl malonate (II) with 1 6-dibromohexane (I) results in diethyl 6-bromohexylmaionate (III). Compound (II) is hydrolyzed to the monoester (IV), followed by condensation with paraformaldehyde in ethanol/piperidine/2-methylquinoline to yield ethyl 8-bromo-2-methyleneoctanoate (V), which is oxidized with permaleic acid to (VI). Subsequent reaction with 4-chlorophenolate produces etomoxir.
