Reaction Steps

A solution of cyanuric chloride (6.44 grams 34.9 mmol; obtained from Aldrich Chemical Co.) in dry tetrahydrofuran (50 milliliters) was added dropwise to a solution of 1,5-bis(4-aminophenoxy)pentane (5.00 grams, 17.46 mmol; prepared as described in Part B of Example VIII) in dry tetrahydrofuran (100 milliliters) at −78° C. The mixture was stirred and allowed to worm up to room temperature for 2 hours. Octylamine (23.0 milliliters, 139 mmol; obtained from Aldrich Chemical Co.) was then added and the mixture was stirred at reflux for 3 hours. The mixture was cooled to room temperature, water was added, and the resulting gummy precipitate (like glue) was filtered. The precipitate was dissolved in chloroform and filtered over silica gel. The volatiles were removed under reduced pressure to afford 1,5-Bis[4-[N-[4,6-bis(N-octylamino)-1,3,5-triazin-2-yl]amino]phenoxy]pentane (7.51 grams, 7.88 mmol, 45 percent yield) as a white solid: IR (KBr) 3410, 3279, 2926, 2855, 1575, 1506, 1423, 1369, 1230, 1031, 810 cm−1.
