To a solution of 5-(2-(2-(2-(2-bromoethoxy)ethoxy)ethoxy)ethoxy)-4-(2-methoxyethoxy)-2-nitrobenzonitrile (0.2 g) in DMF (8 mL) was added 4-hydroxy-5-(2-methoxyethoxy)-2-nitrobenzonitrile (0.1 g) and K2CO3 (0.5 g). The resulting mixture was heated at 80° C. overnight under N2 atmospheres. After reaction finished, the mixture was diluted with water (50 mL) and exacted with EA (3×50 mL). The combined organic layer was dried over Na2SO4, concentrated under reduced pressure, and purification by silica chromatography to give 0.2 g of 4-(2-(2-(2-(2-(5-cyano-2-(2-methoxyethoxy)-4-nitrophenoxy)ethoxy)ethoxy)ethoxy)ethoxy)-5-(2-methoxyethoxy)-2-nitrobenzonitrile. 1H-NMR (400 MHz, CDCl3): δ: 7.92 (s, 1H), 7.84 (s, 1H), 7.35 (s, 1H), 7.26 (s, 1H), 4.35-4.25 (m, 8H), 3.95-3.89 (m, 4H), 3.85-3.78 (m, 4H), 3.77-3.63 (m, 8H), 3.45 (s, 6H).
