Methanesulfonic Acid → HCID 13176884, compound

Participants

Reaction Steps

A mixture of 3.0 g of 6-amidino-2-naphthyl 4-nitrobenzoate methanesulfonate, 0.88 g of methanesulfonic acid, 0.3 g of 10% Pd-C and anhydrous DMF was subjected to catalytic hydrogenation. After absorption of a stoichiometric quantity of hydrogen, the reaction mixture was freed from Pd-C by filtration. After adding ethylether to the filtrate with stirring, the precipitate was collected by filtration and recrystallized from a DMF-ethylether mixture to obtain 3.5 g of a white powder of 6-amidino-2-naphthyl 4-aminobenzoate dimethanesulfonate.
