Reaction Steps
9.86 g (0.085 mole) of diglycolic anhydride and 16.5 g of Schiff base (0.085 mole), prepared from benzyldehyde and benzylamine, are refluxed at 140° C. in 220 ml of xylene for 6 hr. After cooling to 0° C. the solid is collected and washed with ether: 14.5 g (54%) mp 170°-9° C. Recrystallization from methylenechloride (little) and ether gave 11.3 g (43%) of title compound mp 177°-81° C.
