合成路线1
该中间体在本合成路线中的序号:(VII)2) Alternatively, etomoxir can be prepared as follows: Alkylation of 4-chlorophenol with 1,6-dibromohexane (I) yields 1 bromo-6-(4-chlorophenoxy)hexane (VII). Diethyl malonate (II) is alkylated by (VII), yielding (VIII), followed by hydrolysis to the monoester (IX), which is condensed with para formaldehyde/pyridine/piperidine to give ethyl 8-(4-chlorophenoxy)-2-methyleneoctanoate (IX). Oxidation with m-chloroperbenzoic acid produces etomoxir.
