合成路线1
该中间体在本合成路线中的序号：(XXIII)Reaction of 2-nitrovanillin (III) with NH4OH and I2 in H2O/THF yields nitrile (XVIII), which is then condensed with 4-(3-chloropropyl)morpholine hydrochloride (XII) —prepared by alkylation of morpholine (XIX) with 1-bromo-3-chloropropane (XX) in toluene at 84 °C— by means of Cs2CO3 in DMF at 75 °C to give the morpholinopropyl ether (XXI). Reduction of the nitro group in compound (XXI) with Fe and AcOH affords amine (XXII), which by cyclization with ethylenediamine (VII) and sulfur at 100 °C produces the imidazoline derivative (XXIII). Finally, aminoimidazoline (XXIII) is then subjected to ring closure with cyanogen bromide (IX) in the presence of Et3N in CH2Cl2 .
