Procedure
Analogously to Example 1, by reaction of 2.2 g of 3-methylsulfonyl-4-(1-cyclopenten-3-yl)-benzoyl chloride with guanidine, customary working up gives N-diaminomethylene-3-methylsulfonyl-4-(1-cyclopenten-3-yl)benzamide, which can be recrystallized from acetonitrile/diethylether, m.p. 188°-190°.
