Vorschrift

Into solutions of 163 (2.77 g, 0.01 mmol) in 200 mL of dry tetrahydrofuran were added triethylamine (10 mL) and 2-amino-4,5-methylenedioxy acetophenone (148) (1.79 g, 0.01 mmol). The mixtures were stirred at room temperature for 24 h and then evaporated. The residue was purified by column chromatography (SiO2, CH2Cl2/EtOAc=3/1) to give 164.
