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 hydrogen (50 psi), and stirred at RT overnight. The mixture was filtered and the filtrate was concentrated under reduced pressure to give (S)-2-(5-hydroxy-4-(methylamino)pentyl)isoindolin (3.2 g, 97%) which was used without purification. LRMS (M+H+) m/z 263.1.
