合成路线1
该中间体在本合成路线中的序号:(IV)Lithiation of thiazole (I) with butyllithium at -78 C, followed by quenching with chlorotrimethylsilane afforded 2-(trimethylsilyl)thiazole (II). A second lithiation generated the 5-lithio thiazole, which was converted to the stannyl derivative (III) upon reaction with tributylstannyl chloride. Then, palladium-catalyzed coupling of (III) with the iodophenyl oxazolidine (IV) in refluxing dioxan furnished the title compound.

合成路线2
该中间体在本合成路线中的序号:(IX)Reaction of 3-fluoroaniline (I) with benzyl chloroformate provides carbamate (II). The lithium derivative of (II) is then condensed with (R)-glycidyl butyrate (III) to yield the chiral oxazolidinone (IV). After conversion of alcohol (IV) to the corresponding mesylate (V), displacement with NaN3 in hot DMF gives rise to the alkyl azide (VI). Catalytic hydrogenation of azide (VI) furnishes amine (VII), which is further acylated with acetic anhydride, producing acetamide (VIII). Aromatic iodination of (VIII) by means of iodine monochloride in the presence of trifluoroacetic acid gives (IX). Iodide compound (IX) is then converted into the aryl stannane (X) upon treatment with hexamethyl ditin and palladium catalyst
