该中间体在本合成路线中的序号：(III)Mitsunobu coupling of 2-(4-methylpiperazin-1-yl)ethanol (I) with 3,5-dichloro-2,4-dihydroxybenzoic acid (II) in the presence of diisopropyl azodicarboxylate and triphenylphosphine afforded ether (III). Subsequent hydrolysis of the methyl ester group of (III) provided acid (IV), which was coupled with L-phenylalanine methyl ester-HCl (V) employing EDC and HOBt. The title compound was finally isolated as the corresponding dihydrochloride salt.
