실험 절차

In a round bottom flask equipped with an overhead stirrer, 1.16 grams (0.009 mole) of 5-aminouracil was charged along with 6 grams (0.027 mole) of 4,4′-difluorobenzophenone and a N-methylpyrrolidone/N-cyclohexylpyrrolidone solvent mixture (50/50, 20 milliliters). The reaction mixture was then heated to 180° C. for 3 days. A charge of hexanes (100 milliliters) was added to fully induce precipitation, and the solid was isolated by filtration and twice recrystallized from isopropanol. The product was rinsed with isopropanol, suction dried, and vacuum dried in an oven overnight.
