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
