Dicyclohexylcarbodiimide → HCID 13146252, compound

Participants

Reaction Steps

To a solution of 2.5 g of cyclohexylacetic acid in 50 ml of anhydrous pyridine, while being cooled in ice and stirred, was added 4.4 g of DCC. After 30 minutes, 5.0 g of 6-amidino-2-naphthol methanesulfonate was added to the mixture, and stirred for 24 hours at room temperature. The insolubles were removed by filtration and ethyl ether was added to the filtrate. The precipitate was collected by filtration and recrystallized from a dimethylformaldehyde-ether mixture to obtain 3.0 g of a white powder of 6-amidino-2-naphthyl cyclohexylacetate methanesulfonate.
