Reaction Steps

100 g piperidine-1,4-dicarboxylic acid 1-tert-butyl ester was dissolved in 100 mL methanol and 100 mL hydrazine monohydrate was added. The mixture was reflux overnight. The reaction was cooled to RT and then the solvent was removed under vacuum to give 95 g of the desired product. Rf: 0.2 (DCM/MeOH=20/1)
