1-Benzylcyclopropylamine → Tert-butyl 2-(1-benzylcyclopropyl)hydrazinecarboxylate

Participants

Reaction Steps

10.6 g (72.0 mmol) of 1-benzylcyclopropanamine was dissolved in 90 mL of methylene chloride, mixed with 14.3 g (54.5 mmol) of separately prepared t-butyl 3-(trichloromethyl)-1,2-oxaziridine-2-carboxylate under cooling with ice, and stirred at room temperature for 30 minutes. After completion of the reaction, methylene chloride was distilled off under reduced pressure, and the resulting residue was purified by silica gel column chromatography (silica gel 350 g, ethyl acetate:hexane=1:20) to give 4.6 g of the desired product as a brown solid.
