Reaction Steps

2,6-bis[3-(4-aminophenoxy)-2-cyanophenoxy]benzonitrile (p,p-3CN; 6b in FIG. 1) was prepared from 2,6-bis(2-cyano-3-fluorophenoxy)benzonitrile (2.00 g, 5.4 mmol), 4-aminophenol (1.29 g, 11.8 mmol), potassium carbonate (1.78 g, 12.9 mmol), and NMP (32 mL) using the same procedure as Example 3 to obtain 1.52 g (51.5%) of beige solid, m.p. 242.6-243.8° C. (dec.). 1H-NMR (DMSO-d6): 5.18 (s, 4H, Ar—H), 6.57-6.65 (m, 6H, Ar—H), 6.88-6.92 (m, 2H, Ar—H), 7.58-7.61 (t, 2H, Ar—H), 7.77-7.80 (t, 1H, Ar—H). Elemental analysis: Calcd.: C, 71.86; H, 3.84; N, 12.70. Found: C, 71.40; H, 4.00; N, 12.33.
