6-Bromo-1-indanone (VII) is reduced to alcohol (VIII) employing NaBH4. After chlorination of (VIII) with SOCl2, the resultant alkyl chloride (IX) is displaced by heating with ethanolic dimethylamine in a sealed vessel to produce the (dimethylamino)indan (X). Palladium-catalyzed coupling of aryl bromide (X) with trimethylsilyl acetylene (XI) furnishes the silyl acetylene (XII), which is then desilylated to (XIII) with Bu4NF in THF. Finally, condensation between acetylene (XIII), aryl iodide (VI) and carbon monoxide in the presence of palladium catalyst leads to the title quinolone derivative. (1,2)
