実験手順
(2,4-Bis-benzyloxy-5-isopropenyl-phenyl)-[5-(4-hydroxy-1-methyl-piperidin-4-yl)-1,3-dihydro-isoindol-2-yl]-methanone (Example 50F) (1.62 g, 2.75 mmol) was dissolved in methanol (50 mL) and hydrogenated at 50° C. over 10% palladium on charcoal using an H-cube hydrogenation apparatus, under free hydrogen conditions. Concentration afforded the title compound (1.14 g, 100%) as a yellow solid, the NMR and mass spectrometric data of which were as set out in Example 50E.
