Reaction Steps

A solution containing 60 g of 1,17-diphthalimido-3,6,9,12,15-pentaoxaheptadecane (0.118 mol), 14.8 g of hydrazine hydrate (0.296 mol), and 500 ml of ethanol were heated with mechanical stirring in a 100° C. oil bath for three hours. The mixture was then cooled and filtered. The resultant filter cake was washed four times with 300 ml portions of ethanol. The combined filtrates were concentrated to yield 32.35 g of a yellow opaque glassy oil. The evaporative distillation at 150°-200° C. (0.01 mm) gave 22.82 g of a light yellow oil (69% yield). lit. b.p. 175°-177° C. (0.07 mm).
