Participants

Reaction Steps

Replicate the preparation of the ligand used in Ex. 7 except use 0.200 g (1.378 mmol) of 1H-indole-2-carbaldehyde instead of pyrrole-2-carbaldehyde and use 0.158 mL (1.447 mmol) of the N1,N1-dimethylethane-1,2-diamine to give 0.285 g (96%) of N1-((1H-indol-2-yl)methylene)-N2,N2-dimethylethane-1,2-diamine as an off-white solid, which is analytically pure by GC-MS and 1H-NMR: 1H NMR (400 MHz, CDCl3) δ 9.11 (s, br, 1H), 8.19 (s, br, 1H), 7.53 (d, J=7.8 Hz, 1H), 7.23 (d, J=8.0 Hz, 1H), 7.14 (t, J=8.0 Hz, 1H), 7.00 (t, J=7.4 Hz, 1H), 6.65 (s, br, 1H), 3.64 (t, J=6.3 Hz, 2H), 2.53 (t, J=6.7 Hz, 2H), 2.22 (s, 6H).
