実験手順
4,5-Di-(4-bromophenyl)imidazole (2.13 g) was treated with ethyl 8-bromooctanoate (2 g) and K2CO3 (0.5 g) in 2-butanone as described in Example 9 to give ethyl 8-(4,5-di-(4-bromophenyl)imidazol-1-yl)-octanoate (2.2 g, 52%) as a pale yellow oil.; Found: C, 55.13; H, 5.19; N, 5.18; Br; 8.76%; C28H28Br2N2O2 requires: C, 54.76; H, 5.15; N, 5.11; Br, 29.15%
