Reaction Steps
3i was synthesised by an analogous procedure to that described for 3a using 2-[(1H-benzimidazol-2-ylmethoxy)methyl]-1H-benzimidazole (0.7 g, 2.5 mmol) and CrCl3(THF)3 (0.94 g, 2.5 mmol) in 20 ml of THF. Yield 0.96 g, 85%. Anal. Calc. for C16H14Cl3CrN4O (in %): C, 44.01; H, 3.23; N, 12.83. Found C, 44.19; H, 3.38; N, 12.70. IR (KBr, cm−1), υ 3232 (NH, s), υ 1620-1540 (ArC═C, C═N, m), δ 1477-1454 (N—H, s), δ 749 (CH, s). +FAB-MS: (m/z): 400 ([M-Cl]+) 365 ([M-2Cl]), 329 ([M-3Cl]).
