Procedure
The title compound was prepared as in Example 2(a) from 3,4-dichlorobenzoyl cyanide amidinohydrazone obtained in Example 5. The solvent for the ring closure was a mixture of 1-propanol and dimethyl sulfoxide (11). Total yield (from 3,4-dichlorobenzoyl cyanide): 76%; m.p. 222-224° C. (uncorrected).
