Procedure

A mixture of Intermediate D (605 mg, 1.0 mmol), 4-chloro-2-phenylquinoline (481 mg, 2.0 mmol), 60% NaH (80 mg, 2.0 mmol), and dimethylformamide (15 mL) was stirred under argon and heated at 50° C. for 3 hours. After cooling, the mixture was diluted with chlorobenzene (50 mL) and treated with a piece of dry ice to reduce the pH. The volatiles were removed under reduced pressure, and the residue was chromatographed using silica gel and hexane/dichloromethane (2:1) as an eluent to give 4,7-bis(4-(N,N-diphenylamino)phenyl)-2-(2-phenylquinolin-4-yl)-2H-benzo[d][1,2,3]triazole (Example 17) as orange-pink crystals, 640 mg (79%). 1H NMR (400 MHz, CDCl3): δ 8.70 (m, 3H, 2-phenylquinazolin-4-yl), 8.22 (d, J=8.4 Hz, 1H, 2-phenylquinazolin-4-yl), 8.12 (d, J=8.8 Hz, 4H, p-phenylene), 7.97 (ddd, J=8.4, 6.9 and 1.4 Hz, 1H, 2-phenylquinazolin-4-yl), 7.76 (s, 2H, benzotriazole), 7.68 (ddd, J=8.5, 7.0 and 1.1 Hz, 1H, 2-phenylquinazolin-4-yl), 7.53 (m, 3H, 2-phenylquinazolin-4-yl), 7.25-7.30 (m, 8H, Ph), 7.21 (d, J=8.4 Hz, 4H, p-phenylene), 7.16-7.19 (m, 8H, Ph), 7.05 (tt, J=7.3 and 1.1 Hz, 4H, Ph), 2.86 (s, 3H, quinaldine). UV-vis spectrum (dichloromethane): λmax=452 nm. Fluorimetry (dichloromethane): λmax=654 nm.
