Versuchsvorschrift

To a solution of (S)-benzyl 5-(1,3-dioxoisoindolin-2-yl)-1-hydroxypentan-2-yl(methyl)carbamate (5.01 g, 12.65 mmol) in MeOH (100 mL) was added Pd/C (1.0 g). The mixture was transferred to an autoclave reactor, charged with 50 psi of hydrogen, and stirred overnight. The mixture was filtered, and the filtrate was concentrated under reduced pressure to give (S)-2-(5-hydroxy-4-(methylamino)pentyl)isoindoline-1,3-dione (3.2 g, 97%). LRMS (M+H+) m/z 263.1
