Dicyclohexylcarbodiimide → 4-Amidino-2-benzoylphenyl 4-dimethylaminobenzoate methanesulfonate

Participants

Reaction Steps

In 50 ml of dried pyridine, was dissolved 1.65 g of 4-dimethylaminobenzoic acid followed by the addition of 3.1 g of DCC. After 30 minutes of stirring, 3.36 g of 4-amidino-2-benzoylphenol methanesulfonate was added to the mixture and the mixture was further stirred overnight. The reaction mixture was removed of the insolubles by filtration and recrystallized from ethanol to yield 1.2 g of 4-amidino-2-benzoylphenyl 4-dimethylaminobenzoate methanesulfonate.
