Abstract

The compound of formula <FORM:0975773/C1/1> is prepared by reacting 2-amino-5-nitrophenol with sebacic acid ethyl ester acid chloride to give 2-(o - carbethoxy-pelargoylamino)-5-nitrophenol which is then reduced to the corresponding 5-amino compound and this product condensed with 2-thenoyl chloride. The compound of formula <FORM:0975773/C1/2> is prepared by reacting 2-amino-5-nitrophenyl with 2-thenoyl chloride to give 2-thenoylamino-5-nitrophenol which is reduced to 2-thenoylamino-5-aminophenol and this product reacted with 2-(2-hexadeceny)-succinic anhydride. The compound of formula <FORM:0975773/C1/3> is prepared by reacting 2-thenoylamino-5-aminophenol with p-hexadecyloxybenzoyl chloride. Specifications 478,985, 562,205, 797,141 and 906,908 are referred to.
