Participants

Reaction Steps

A solution of anhydrous hydrazine (1 ml) was added to a stirred mixture of anhydrous ethanol (30 ml) and methylene chloride (20 ml) containing N,N′-bis(t-butyloxycarbonyl)-N,N′-bis(6-phthalimidohexyl)-1,2-diaminoethane (2.8 g; example 9). The reaction was continued overnight and the precipitated phthalazinedione by-product was removed by filtration. The filtrate on concentration at reduced pressure gave the title compound (1.5 g) as an oil.
