Pyridine → HCID 101438404, compound

Participants

Reaction Steps

To 20 g of FN-1 in 1 L of DMSO, was added 20 ml of dehydrated pyridine and 1 L of acetic anhydride. The solution was allowed to react for 12 hours. The solution was then allowed to settle and the supernatant fluid was removed by decantation. The residual solution containing a solid on the bottom of the beaker was added to a large amount of doubly distilled, deionized water. Next, the solid was filtered, washed with deionized water three times, and then dried to obtain 25 g of a solid of FN-2 (yield: 88%). 3 g of this FN-2 was dissolved in 100 ml of dimethyl sulfoxide, and the solution was poured in a tray and then dried at 60° C. After 12 hours, the polymer was removed to obtain a free standing film.
