3.25 g of 2-methoxy-4-(phenylamino)-benzenediazonium bisulfate (Diversitec, Fort Collins, Colo.) in 50 ml of water was neutralized with 0.8 g of sodium bicarbonate in 25 ml water. 3.45 g of sodium hexadecyl sulfate (TCI America, Portland, Oreg., USA) was dissolved in 150 ml of water at 50° C. The solution of the diazonium salt as slowly added to the hexadecyl sulfate solution with stirring. The reaction mixture was stored in the dark at 0–5° C. for 12 hours. The resulting precipitate was filtered off and dried in vacuum. Yield: 5.4 g.
