Reaction Steps

A mixture of (±)-5′-nitro-spiro[imidazolidine-4,2′-indane]-2,5-dione (1.4 g, 5.66 mmol, described in Intermediate 6), 4-methoxybenzyl alcohol (0.94 g, 6.80 mmol), diethyl azodicarboxylate (1.48 g, 8.49 mmol), and triphenylphosphine (2.23 g, 8.49 mmol) in THF (15 mL) was stirred at ambient temperature for 3 days. The solvent was removed under reduced pressure and the residue was partitioned between saturated aqueous NaHCO3 (15 mL) and CH2Cl2 (50 mL). The organic layer was dried (Na2SO4), filtered, and concentrated under reduced pressure. The crude product was purified by silica gel chromatography, eluting with a gradient of hexane:EtOAc—90:10 to 60:40, to give the title compound. MS: m/z=368 (M+1).
