Fifty parts of dimethyl 5-nitroisophthalate and 130 parts of N,N-diethyl-1,3-propanediamine were reacted for about four hours at 80 to 100° C. under a slight vacuum. After confirming the disappearance of the starting material dimethyl 5-nitroisophthalate and monoamide compounds, the excess N,N-diethyl-1,3-propanediamine was removed under vacuum, yielding 92 parts of 5-nitroisophthalic acid bis-3-diethylaminopropylamide.
