Versuchsvorschrift
2,4-Dichloroaniline (2.380 g) was dissolved in pyridine (20 ml), and to the solution was added dropwise ethyl chloroformate (1.685 ml) under ice-cooling. After the mixture was stirred for 2 hours, 1N hydrochloric acid was added. The precipitated crystals were filtered, washed with water and then dried to give the title compound (3.4055 g, 99%).
