Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Guanidine | HCID 3520 | — |
| Reactant | 3-Methylsulfonyl-4-(1-cyclopenten-3-yl)-benzoyl chloride | HCID 19688268 | — |
| Product | N-diaminomethylene-3-methylsulfonyl-4-(1-cyclopenten-3-yl)benzamide | HCID 19688175 | — |
Reaction Steps
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°.
