The mixture is heated to 180° C. for 30 minutes. Then the mixture is diluted with diethylether, washed with water and brine and dried (MgSO4). The solvent is evaporated and the residue is purified by HPLC on reversed phase to give the title compound. Yield: 32 mg; LC (method 8): tR=0.47 min; Mass spectrum (ESI+): m/z=349 [M+H]+.
