실험 절차

To a solution of 2-chloro-6-fluorobenzenamine (5.0 g, 34 mmol) in chlorobenzene (52 mL) was added carbonothioic dichloride (thiophosgene) (5.1 g, 45 mmol) and DMF (0.27 mL). The reaction mixture was refluxed for 2 h and then concentrated to leave the title compound as a brown oil (6.15 g), which was used in Step C without further purification.
