Procedure

Using the general method of Example 181 1-(4-aminobutyl)-2-(2-methoxyethyl)-1H-imidazo[4,5-c]quinolin-4-amine (1.5 g, 4.78 mmol) was reacted with 2-quinoxalinecarboxylic acid (1.0 g, 5.74 mmol) to provide 270 mg of N-{4-[4-amino-2-(2-methoxyethyl)-1H-imidazo[4,5-c]quinolin-1-yl]butyl}quinoxaline-2-carboxamide as a yellow crystalline solid, m.p. 85-87° C. Analysis: Calculated for C26H27N7O2: % C, 66.51; % H, 5.80; % N, 20.88. Found: % C, 66.12; % H, 5.70; % N, 20.62.
