The reaction mixture was stirred over night at room temperature. After evaporation of the solvent the residue was dissolved in methanol and given on a PoraPak Rxn CX column. The column was washed with 100 mL methanol, and the product was eluted with methanol/ammonia. The solvent was removed, and the residue was purified by HPLC yielding 32.8 mg of the title compound.
