Reaction Steps

The synthesis generally followed the method of Kern et al., Makrol. Chem., 180, 2539 (1979). 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 is heated with mechanical stirring in a 100° C. oil bath for three hrs. The mixture is cooled and filtered. A resultant filter cake is washed four times with 300 mL portions of ethanol. The combined filtrates are concentrated to yield 32.35 g of a yellow opaque glassy oil by evaporative distillation at 150-200° C. (0.01 mm of vacuum). The result is 22.82 g of a light yellow oil (69% yield). b.p. 175-177° C. (0.07 mm).
