実験手順
A mixture of the product from step (i) (40 g) and 5% Pd—C (3 g) in EtOAc were hydrogenated at 3 Bar for 48 h. The mixture was filtered through celite and evaporated under reduced pressure. The residue was purified by column chromatography eluting with 30% EtOAc/iso-hexane to afford the subtitle compound, 23.35 g.
