반응 단계
To a solution of 4-fluoroanthranilic acid (0.882 g, 5.69 mmol) in methylene chloride (50 ML) and acetic acid (10 mL) is added tert-butyl hypochlorite (0.71 mL, 6.25 mmol) solution in dichloromethane (1 mL) dropwise over 1 minute. After 90 minutes, the reaction mixture is washed with water and brine. The organic layer is dried over MgSO4, filtered, and the filtrate concentrated to afford 5-chloro-4-fluoroanthranilic acid (1.20 g). MS CI: m/e 188 (M+).
