Versuchsvorschrift
The title compound was prepared as in Example 2(a) from 2,4-dichlorobenzoyl cyanide amidinohydrazone obtained in Example 3. The solvent for ring closure was a mixture of 1-propanol and dimethylsulfoxide (5:1). Total yield (from 2,4-dichlorobenzoyl cyanide): 55%; m.p. 220-222° C. (uncorrected).
