合成路线1
该中间体在本合成路线中的序号：(I)By condensation of 4-(2-quinolinylmethoxy)benzaldeyde (I) with 2-hydroxy-5(1H-tetrazol-5-yl)acetophenone (II) by means of KOH in ethanol/water. The intermediates (I) and (II) have been obtained as follows: Benzaldehyde (I): By condensation of 2-(chloromethyl)quinoline (III) with 4-hydroxybenzaldehyde (IV) by means of K2CO3 in hot DMF. Acetophenone (II): The acetylation of 4-hydroxybenzonitrile (V) with acetic anhydride/sulfuric acid and AlCl3 gives 5-cyano-2-hydroxyacetophenone (VI), which is then cyclized with sodium azide and ammonium chloride in hot DMF.
