Versuchsvorschrift

Three grams (0.016 mol) of 2,6-difluoro-benzoyl isocyanate were added to a solution of 2.95 gm (0.015 mol) of 2,4-difluoro-3,5-dichloroaniline in 50 ml of toluene. The solution thus obtained was stirred for 15 hours at room temperature. Thereafter, the product which precipitated during that time was removed by suction filtration and dried.
