実験手順
A suspension of 53 g. of 6-(o-chlorophenyl)-1,2,4-triazin-3(2H)-one in 400 ml. of chloroform is cooled in an ice bath and 400 ml. of phosphorus oxychloride is added followed by 3 g. of N,N-dimethylformamide. The mixture is refluxed overnight and treated as described in Example 12, giving 3-chloro-6-(o-chlorophenyl)-1,2,4-triazine as white needles.
