실험 절차

3-Piperidin-4-yl-3,4-dihydro-1H-quinazolin-2-one (0.2 g, 0.87 mmol) was dissolved in acetic acid (2 mL). To this solution was added a solution of bromine (1.8 mL, 35.14 mmol) in acetic acid (0.5 mL) dropwise over 5 min. After stirring for at room temperature for 1 h, the reaction mixture was diluted with methylene chloride, washed with water (2×), brine (2×), dried over sodium sulfate, filtered, and concentrated to afford 0.16 g (59%) which was used immediately without further purification. LC/MS: tR=0.91 min, 310.15 (MH)+.
