Procedure

To a solution of 1.1 g of phenoxyacetic acid in 50 ml of pyridine, was added 2.2 g of DCC. The mixture was stirred at room temperature for 30 minutes, then admixed with 2.0 g of 6-amidino-2-naphthol methanesulfonate, and again stirred overnight at room temperature. The insolubles were removed by filtration, 500 ml of ethyl ether was added to the mother liquor and thoroughly stirred to precipitate a solid substance which was collected by filtration and recrystallized three times from methanol to obtain 0.3 g of 6-amidino-2-naphthyl phenoxyacetate methanesulfonate.
