실험 절차

A mixture of 7,8-dihydro-1H,6H-quinoline-2,5-dione (20.4 g, 125.0 mmoL), benzyl bromide (17.8 mL, 150 mmoL) and 20.8 g, 75 mmoL) in toluene (250 mL) was stirred at room temperature for 3 days under the protection from light. The reaction was stopped, filtered through celite and rinsed with a mixture of methylene chloride and methanol. The filtrate was concentrated and trituated in petroleum ether (150 mL). Filtration of the mixture provided the desired product (29.4 g, 92%).
