실험 절차
A solution of 460 mg of ethyl (E)-3-[5′-(3-heptyl-1-methylureido)-2′-methylbiphenyl-4-yl]acrylate (prepared in step 21f) in 10 ml of methanol is stirred for 12 hours at room temperature in the presence of 100 mg (22% by mass) of 10% palladium-on-charcoal under a hydrogen atmosphere. The palladium is filtered off and the solvent is evaporated off. The oil is used directly in the following step.
