In an alternative procedure, Wadsworth-Emmons condensation of 5-fluoroindan-2-one (VI) with triethyl phosphonoacetate gave the indeneacetate (VII), which was reduced to aldehyde (VIII) employing diisobutylaluminum hydride. Strecker reaction of aldehyde (VIII) with NaCN and NH-4-Cl produced amino nitrile (IX). This was reduced to diamine (X) using LiAlH4, and then condensed with formamidine acetate to produce imidazoline (XI). Finally, catalytic hydrogenation of indene (XI) over Pd/C provided the title indane derivative.
