実験手順
0.17 g (0.5 mmol) of the compound from Example 22 were dissolved in 25 ml 90% acetic acid followed by addition of 30 mg platinum(IV) oxide. The mixture was filled into an autoclave and hydrogenated for 4 h at room temperature and a pressure of 20 atm. The catalyst was removed by filtration and the solvent evaporated under reduced pressure. The residue was treated with water and neutralized with sodium carbonate followed by extraction with dichloromethane. The organic layer was dried over sodium sulfate and concentrated in vacuo to leave the pure title compound.
