반응 단계
To a solution of 74.08 g (0.50 mole) 2-chromanone in 150 ml carbon disulfide at 0° C. was added dropwise over 15 minutes, 79.91 g (0.50 mole) bromine. Stirring was continued at 0° C. for ten minutes and at room temperature for 2 days. The resulting mixture was filtered, the crystals air dried to afford 96.8 g (85%) of colorless material, m.p. 103°-105° C. (2 crops).
