该中间体在本合成路线中的序号:(VI)The reaction of 4-fluorobenzoyl chloride (I) with N,O-dimethylhydroxylamine (II) in pyridine gives the N-methylhydroxamate (III), which is condensed with 5-bromo-1H-indole (IV) by means of KH and t-BuLi yielding the ketone (V). The alkylation of (V) with ethyl iodide and NaH in DMF affords (1-ethylindol-5-yl)(4-fluorophenyl)methanone (VI), which is reduced with NaBH4 in methanol to the corresponding carbinol (VII). Finally, this compound is treated with carbonyl diimidazole in THF.
