실험 절차

A 1M solution borane in THF (28.7 mL, 28.7 mmol) was added to N′-(1-tert-Butyl-piperidin-4-ylidene)-hydrazinecarboxylic acid tert-butyl ester. The mixture was stirred for 16 h, and then 40 mL of 6M HCl was added. The mixture was heated to 60° C. for 30 min. The mixture was concentrated and 200 mL of petroleum ether was added, followed by powdered NaOH (5 g). The slurry was stirred manually for 30 min, and then the mixture was dried with MgSO4, filtered, and concentrated to give 1.21 g of (1-tert-butyl-piperidin-4-yl)-hydrazine (1.21 g).
