合成路线1
该中间体在本合成路线中的序号:(XIII)Heck reaction of aryl bromide (IX) with vinyl tributyltin (X) in the presence of palladium catalyst gave the vinyl tetrahydronaphthalene (XI), which was converted to the primary alcohol (XII) by means of hydroboration with borane in THF followed by oxidative treatment with H2O2 and NaOH. Reaction of alcohol (XII) with p-toluenesulfonyl chloride and Et3N produced the corresponding tosylate (XIII) (1). This was then condensed with 6-fluoro-3-(4-piperidinyl)benzisoxazole (XIV), yielding adduct (XV). Finally, basic hydrolysis of the ester group of (XIV) provided the title carboxylic acid.

合成路线2
该中间体在本合成路线中的序号:(XIII)Heck reaction of aryl bromide (IX) with vinyl tributyltin (X) in the presence of palladium catalyst gave the vinyl tetrahydronaphthalene (XI), which was subjected to oxidative double-bond cleavage to aldehyde (XII) using NaIO4 in the presence of a catalytic amount of OsO4. Aldehyde reduction with NaBH4 provided alcohol (XIII). This was then converted to the corresponding bromide (XIV) by treatment with carbon tetrabromide and triphenylphosphine.
