Dicyclohexylcarbodiimide → HCID 178505336, compound

Participants

Reaction Steps

To a solution of 3.0 g of 4-guanidinocinnamic acid methanesulfonate in 30 ml of anhydrous pyridine, was added 2.4 g of DCC. To the mixture, while being cooled in ice and stirred, was added 2.8 g of 6-amidino-2-naphthol methanesulfonate. After having been stirred for 24 hours, the reaction mixture was filtered to remove insolubles and the filtrate was mixed with ethyl ether to separate an only substance which was left standing at room temperature to crystallize. Upon recrystallization from a methanol-ethyl ether mixture, there was obtained 2.4 g of 6-amidino-2-naphthyl 4-guanidinocinnamate dimethanesulfonate.
