実験手順
10 g of the urethane which had previously been treated in this way were dissolved in 60 g o-xylene. The solution is heated to 80° C. and mixed with 2 g of a 2%, by weight, aqueous potassium permanganate solution. The mixture was stirred intensely for 30 minutes at 80° C. The hot organic phase was then separated from the solid and aqueous constituents. The organic phase was concentrated by distilling off a proportion of the xylene to half of its original volume, and the purified 2,4-bis-(ethoxycarbonylamino)-toluene was obtained in a virtually quantitative yield from the concentrated solution by crystallization.
