合成路线1
该中间体在本合成路线中的序号：(IV)The earlier synthesis starts with the reaction of 4-chloro-7-(trifluoromethyl)quinoline (I) with 4-aminobenzoic acid (II) in ethanol-HCl giving 4-(4-carboxyphenylamino)-7-(trifluoromethyl)quinoline (III), which is converted to its acyl chloride (IV) by treatment with SOCl2. The reaction of (IV) with piperazine (V) yields 1-[4-[7-(trifluoromethyl)quinolin-4-ylamino]benzoyl]piperazine (VI), which is finally acylated with 4-fluorobenzenesulfonyl chloride (VII) to give U-54669 F. However, this method is not economically efficient, since the most expensive compound [quinoline (I)] is already used in the first step of the synthesis.
