Versuchsvorschrift

Methyl 4-(4-bromo-2-chlorophenylamino)-5,6-dichloronicotinate (1.690 g, 4.14 mmol) was suspended in 30 ml DMF and the suspension was heated until everything went into solution. It was cooled down to room temperature and to that solution was added solid sodium azide (0.533 g, 8.2 mmol). The yellow solution was stirred for 17 h at room temperature and was diluted with water. The precipitate was filtered, washed with water and hexanes and dried in oil-pump vacuo at 50° C. for 2 h to obtain the title compound as a light-brown solid (1.5422 g, 90%). 1H-NMR (300 MHz, DMSO-D6): δ=9.85 (s, 1H), 8.90 (s, 1H), 7.80-7.79 (d, 1H), 7.46-7.40 (dd, 1H), 6.95-6.90 (d, 1H), 3.80 (s, 3H).
