合成路线1
该中间体在本合成路线中的序号：(XVIII)In a related method, electrophilic bromination of 2,3-dichlorophenol (XI) gave (XII). Heck reaction of bromide (XII) with methyl acrylate (XIII) produced the cinnamic acid derivative (XIV). Sulfonylation of the phenolic hydroxyl of (XIV) with trifluoromethanesulfonic anhydride in pyridine furnished the aryl triflate (XV). This was coupled with the silyl sulfide intermediate (II) in the presence of CsF to produce the diaryl sulfide (XVI). After methyl ester (XVI) hydrolysis, the resultant cinnamic acid (VIII) was coupled with methyl isonipecotate (XVII) to furnish amide (XVIII). The title compound was then obtained by methyl ester (XVIII) hydrolysis with LiOH, followed by treatment with methanolic NaOH.
