Reaction Steps

A mixture of [(S)-1-(1,3-dioxo-1,3-dihydro-isoindol-2-ylmethyl)-butyl]-carbamic acid tert-butyl ester (2.80 g, 8.42 mmol) and hydrazine monohydrate (3.0 mL, 60.0 mmol) in EtOH (50 mL) and DCM (75 mL) is stirred at RT for 48 h. The precipitated solid is collected by filtration and washed with DCM to afford the crude product as a white solid that is used without further purification.
