Procedure

A mixture of 42.4 g of 8-(4-nitro-2-sulfobenzamido)-1,3,6-naphthalenetrisulfonic acid, tetrasodium salt, and 1.5 g of 10% palladium-on-carbon in 150 ml of water was hydrogenated in a Parr shaker for one hour. The mixture was filtered through diatomaceous earth. The filtrate was concentrated to about 130 ml and poured with vigorous stirring into 500 ml of absolute ethanol. The resulting gum was collected by filtration through diatomaceous earth and then dissolved from the diatomaceous earth with water. The aqueous solution was concentrated to 15 ml and then diluted with 85 ml of ethanol giving a gum which was stirred with absolute ethanol giving a solid which was dried overnight in a pistol at 110° C. giving 36.15 g of 8-(4-amino-2-sulfobenzamido)-1,3,6-naphthalenetrisulfonic acid, tetrasodium salt.
