Versuchsvorschrift
To 1,2-dimethylindole-3-carboxaldehyde (11.50 g, 66.4 mmole) was added a solution of 2 M methylamine in methanol (100 mL, 200 mmole). The reaction was stirred for 4 h at RT then was concentrated to dryness to afford the crude title compound: 1H NMR (400 Hz, CDCl3) δ 8.55 (d, J=1.4 Hz, 1 H), 8.16 (d, J=7.5 Hz, 1 H), 7.42 (d, J=7.8 Hz, 1 H), 7.15 (t, 1 H), 7.07 (t, 1 H), 3.68 (s, 3 H), 3.41 (s, 3 H), 2.55 (s, 3 H).
