Dicyclohexylcarbodiimide → HCID 13146238, compound

Participants

Reaction Steps

To a solution of 4.3 g of n-pentadecanoic acid in 50 ml of anhydrous pyridine, while being cooled in ice, was added 4.4 g of DCC. After stirring for 30 minutes, 5.0 g of 6-amidino-2-naphthol methanesulfonate was added to the mixture and further stirred overnight at room temperature. The precipitate was collected by filtration, washed with ethyl ether, then with acetone, dissolved in a methanol-dimethylformamide mixture, freed from the insolubles by filtration, and concentrated under reduced pressure. The crystals formed upon addition of ethyl ether were recrystallized from methanol to obtain 3.0 g of a white powder of 6-amidino-2-naphthyl pentadecanoate methanesulfonate.
