Versuchsvorschrift

2.3 g of rac-benzyl [2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-3-isopropoxypropyl]carbamate (5.6 mmol, 1 equivalent) were dissolved in 30 ml of ethanol, 7.3 ml of 40% strength aqueous methylamine solution (84.4 mmol, 15 equivalent) were added and the mixture was stirred at 60° C. overnight. The reaction mixture was concentrated and the residue was then chromatographed on silica gel (Biotage Isolera; mobile phase: dichloromethane/methanol gradient). This gave 730 mg (49% of theory) of the title compound.
