Reaction Steps

1-hydroxy-4-iodo-2'-tetradecyloxy-2-naphthanilide (9 g) and 1-phenyl-5-mercapto-tetrazole potassium salt (3 g) were solubilized im dimethylformamide (25 ml). The solution was heated at 90° C. for 1 hour under stirring. After adding ethanol (25 ml), a white solid precipitated. The solid collected by filtration was crystallized from ethanol. The yield was 90% of 1-hydroxy-4-(1-phenyl-5-tetrazolylthio)-2'-tetradecyloxy-2-naphthanilide of formula ##STR11##
