The resulting suspension was heated at refluxing temperature and allowed to react for 48 h. After cooling to room temperature, the reaction mixture was partitioned between ethyl acetate and water. The organic phase was washed repeatedly with water, dried over sodium sulfate, filtered and concentrated by rotary evaporation to yield 3.6 g bis[6-{4-[(1E)-3-(4-pentyloxyphenoxy)-3-oxoprop-1-enyl]phenoxy}hexyl]2,2 bis(4-nitrobenzyl)malonate.
