2,9-Dichloro-1,10-phenanthroline was prepared by a previously published method [1]. 2,9-Dichloro-1,10-phenanthroline (50 mg) was placed in a flask where the temperature was raised 150 °C with oil-bath, and aniline was introduced under N2 gas. The temperature was raised to 250 °C and maintained for 5 hours. The mixture was purified by recrystalization from methanol, to give 2,9-diphenylamino-1,10-phenanthroline as a dark brown crystal (30 mg, yield: 30.0%).
1H-NMR (300MHz, d-TFA/CDCl3, V:V=1:1): 8.73 (2H, d, J=9.5), 8.24 (2H, s), 7.87 (6H, t), 7.69 (6H, t).
IR (KBr, cm-1): 410 (w), 500 (w), 589 (w), 613 (w), 689 (w), 730 (w), 762 (m), 846 (m), 1028 (w), 1076 (w), 1153 (w), 1209 (w), 1257 (w), 1284 (w), 1327 (w), 1362 (m), 1386 (w), 1397 (w), 1441 (m), 1453 (s), 1491 (m), 1510 (m), 1547 (s), 1577 (m), 1599 (m), 1642 (s), 1649 (s), 3279 (w), 3321 (m).
UV-Vis (1 , nm, in CH3OH): 206.5, 225.5, 277.5, 347.5.
FAB-MS ([M+1]+): 363.
