合成路线1
该中间体在本合成路线中的序号：(XII)Reduction of 11-oxo-6,11-dihydrodibenz[b,e]oxepin-2-acetic acid methyl ester (IV) with lithium aluminum hydride gives 11-hydroxy-2-(2-hydroxyethyl)-6,11-dihydrodibenz[b,e]oxepin (X), whose primary hydroxyl group is protected with triphenylchloromethane in pyridine to yield 11-hydroxy-2-(2-triphenylmethoxyethyl)-6,11-dihdrodibenz[b,e]oxepin (XI). Oxidation of (XI) with potassium permanganate affords 11-oxo-2-(2-triphenylmethoxyethyl)-6,11-dihydrodibenz[b,e]oxepin (XII), which is treated with 3-(dimethylamino)propylmagnesium chloride (XIII) to give 11-[3-(dimethylamino)propyl]-11-hydroxy-2-(2-triphenylmethoxyethyl)-6,11-dihydrodibenz[b,e]oxepin (XIV). Elimation of water with phosphorous oxychloride yields 11-[3-(dimethylamino)propylidene]-2-(2-triphenylmethoxyethyl)-6,11-dihydrodibenz[b,e]oxepin (XV), which is deprotected with p-toluenesulfonic acid to 11-[3-(dimethylamino)propylidene]- 2-(2-hydroxyethyl)-6,11-dihydrodibenz[b,e]oxepin (XVI). Finally, compound (XVI) is oxidized with Jones reagent.
