Reaction Steps

To a stirred solution of N-(3,5-dichloro-phenyl)-N′-[2-(4-iodo-phenyl)-pent-4-enyl]-ethane-1,2-diamine (0.386 g, 0.81 mmol) in toluene (10 mL) was added CDI (0.18 g, 1.1 mmol, 1.4 eq). The mixture was heated to 100° C. for 16 h, then cooled to room temperature, diluted with EtOAc (25 mL) and washed twice with saturated aqueous NaCl (25 mL). The organic extracts were dried over sodium sulfate, filtered and concentrated by rotary evaporation to give a dark brown oil. The crude product was purified by flash column chromatography eluting with 10% EtOAc/hexanes to give 1-(3,5-dichloro-phenyl)-3-[2-(4-iodo-phenyl)-pent-4-enyl]-imidazolidin-2-one (0.128 g, 0.255 mmol, 30%) as a pale foam. 1H NMR (300 MHz, CDCl3): δ 7.74 (d, 2H), 7.54 (d, 2H), 7.20 (m, 3H), 5.75 (m, 1H), 5.10 (m, 2H), 3.74 (m, 3H), 3.38 (m, 2H), 3.22 (m, 1H), 3.08 (m, 1H), 2.50 (m, 2H).
