실험 절차

3,3,7-Trimethyl-3,4-dihydroquinoxalin-2(1H)-one (0.4 g, 2.1 mmol) were dissolved in 10 ml of anhydrous pyridine, and the stirred solution was treated at room temperature with 0.24 ml (2.2 mmol) of isopropenyl chloroformate. The mixture was stirred for 6 hours at room temperature and treated with water, the precipitate which formed was filtered off with suction, washed with water and dried. This gave 0.4 g (69%) of colorless crystals of melting point 185° C.
