Procedure

First, 707 mg of 1,4-bis(6-ethoxycarbonyl-3-hexenyl)benzene was dissolved in 14 ml of ethanol, and after adding 70 mg of 5% palladium/carbon, the mixture was stirred under hydrogen flow at a room temperature for 2 hours, filtered to remove the catalyst, and concentrated under a reduced pressure to obtain 601 mg of 1,4-bis(6-ethoxycarbonylhexyl)benzene as a colorless liquid.
