3 g (0.005 mol) of the 3,5-dinitro-N-(4-(3-pentadecylphenoxy)phenyl)benzamide thus prepared is dissolved in 20 mL of ethanol and reduced using 0.1 g 10% Pd/C catalyst at 40° C. and 40 psi hydrogen pressure until no more hydrogen is absorbed. The catalyst is then filtered and the diamine recrystallized from the filtrate to yield 3,5-diamino-N-(4-(3-pentadecylphenoxy)phenyl)benzamide, of the formula
