Reaction Steps

To an ice-cold solution of ethyl 4-(1,3-dioxoisoindolin-2-yl)-1-methylcyclohexanecarboxylate (0.30 g, 0.95 mmol) in EtOH (20 mL) was added hydrazine hydrate (0.115 mL, 2.38 mmol) and the resulting mixture heated up to 80° C. for 2-3 h. After the completion of reaction (by TLC), solvent was evaporated under reduced pressure, water added (20 mL), extracted with EtOAc (3×50 mL) and the combined organics washed with brine, dried (Na2SO4), filtered and concentrated under reduced pressure to obtain the desired product as a viscous liquid (0.18 g, crude). MS: 186.20 [M+H]+.
