La carbométhoxylation dela nitroguanidine modifie sa réactivité vis-à-vis d'une amine aliphatique en solution aqueuse. Tandis que la nitroguanidine fournit 30 à 50% d'alcoyl-nitroguanidine (Davis), le groupe nitro du produit acylé est éliminé et la butyl-carbo-méthoxy-guanidine a été obtenue avec un rendement de 30%. La N-nitro-N′-carbométhoxy-N′-butylguanidine réagit de méme en donnant 20% de d
