50 mmol of 2,4,6-tribromoaniline were dissolved in 20 ml of tetrahydrofuran. A solution of 50 mmol of toluenesulfonyl isocyanate in 20 ml of tetrahydrofuran was added dropwise at room temperature, and the stirred reaction mixture was subsequently kept at 40° C. for 3 hours. The precipitated crystals were filtered off under suction. After recrystallization from toluene, the product had a melting point of 230° C.
