실험 절차
2-Bromo-4-chloro-6-fluoroaniline (5 mmol, 1.125 g), bis(trichloromethyl) carbonate (1.7 mmol, 0.50 g) and 1,4-dioxane (10 ml) were mixed together and the mixture was heated to 100° C. for 15 minutes; the mixture was then cooled to room temperature and it was filtered. The filtrate was concentrated to afford a mixture of products (2.2 g) containing the title compound, M++MeO=283 (LC-MS run in methanol).
