After shaking at 110° C. for 18 h, the reaction mixture was filtered and the solvent evaporated. The obtained residue was purified by flash chromatography (eluent: pure EtOAc for 4CV, then from pure EtOAc to EtOAc/MeOH 9:1 in 10 CV, then EtOAc/MeOH 9:1 for 10 CV; 12M column) to obtain 14.5 mg of our target compound that was further purified on a SCX cartridge and eluted with a 2M solution of ammonia in MeOH. The resulting solution was evaporated in vacuo to obtained 10.9 mg of title compound as a white solid.
