EXAMPLE '. -

  
In a mixture of 130 parts of phosgene and 1000 parts of chloroform, 73 parts of dimethylformamide are slowly added with cooling. The mixture is stirred for a further 2 to 3 hours, then 162 parts of isatin-oxime are introduced at room temperature. Gas evolution immediately occurs. When the latter weakens, the mixture is brought to reflux temperature. After 2 to 3 hours, the reaction is terminated. After cooling the reaction mixture,
