合成路线1
该中间体在本合成路线中的序号：(I)1-(3,4-Dimethoxyphenyl)-2-propanol (I) is condensed with 4-nitrobenzaldehyde. The resulting 1-(4-nitrophenyl)-3-methyl-6,7-dimethoxyisochromane (II) is oxidized with Jones reagent to obtain 2-acetonyl-4,5-dimethoxy-4'-nitrobenzophenone (III). Then 1-(4-nitrophenyl)-3-methyl-6,7-dimethoxy-2-benzopyrylium perchlorate (IV) is produced by the conventional procedure, from which intermediary, with the help of hydrazine hydrate and reduction. GYKI-52322 is prepared.
