실험 절차

A mixture of 7-chloro-2,3-dihydro-10-hydroxypyridazino[4,5-b]quinoline-1,4-dione (0.60 g, 2.3 mM), as prepared in Example 2, and hydrocinnamoyl chloride (1.15 g, 6.84 mM) in pyridine (9 mL) was refluxed for 1 hr. Upon cooling to room temperature, the solution solidified. After 2 hr at room temperature, the mixture was diluted with water (60 mL) and the solids broken up with a glass rod to provide a free-flowing aqueous suspension which was stirred for 1 hr. The solids were collected, washed with water (10 mL), and resuspended in 50% aqueous methanol (60 mL). After stirring for 15 minutes, this suspension was filtered and the collected solids were washed with 50% aqueous methanol (10 mL) and then sucked dry under a stream of nitrogen to provide a tan solid. This material was dried for 2.5 days in vacuo (50 mTorr) at 100° C. and then was recrystallized from dimethylsulfoxide/methanol. The title compound was obtained (0.40 g, 44%), after drying 24 hr in vacuo (50 mTorr) at 100° C., as an off-white powder, mp>300° C.
