Procedure
The reaction and workup were carried out in the same manner as described in Example 8, using 4-bromoveratrole (0.9 mL, 7.0 mmol), n-butyl lithium (4.38 mL of 1.6 M solution in hexane), terephthalaldehydic acid N-cyclopentyl-N-cyclohexyl amide (1.9 g, 6.36 mmol). The crude product was chromatographed on silica gel using mixtures of ethyl acetate and hexane to give the title compound as an amorphous solid.
