Versuchsvorschrift

To the solution of 3-(3,5-dibutoxy-4-hydroxyphenyl)acrylic acid (130 mg, 0.421 mmol), 4-(2-aminoethyl)-2,6-di-t-butylphenol (110 mg, 0.441 mmol) and HOBT (70 mg, 0.51 mmol) in MeCN 10 ml were DCC at 0° C. After 5 minutes, the solution was stirred for 2 hours at room temperature. And then the precipitate was removed by filtering it through a celite layer and the solution was poured into CH2Cl2. The solution was washed with 2N HCl and saturated NaHCO3 solution and the water was dried over anhydrous magnesium sulfate and filtered. The obtained filtrate was vacuum concentrated to give the residue, which was purified by column chromatography (EtOAc:Hexane=1:3), yielding 208 mg (91%) of the title compound.
