Versuchsvorschrift

This compound was produced by modifications of the methods used by Murakami, et. al. (Tetrahedron, 1997, 53, 1593-1606) starting with (1-benzyl-1H-indol-2-yl)-methanol (1.13 g, 4.76 mmol) and manganese dioxide (5.6 g). The crude material was purified by flash chromatography through silica gel using diethyl ether/hexanes (0/100 gradient to 10/90) to give 1-benzyl-1H-indole-2-carbaldehyde (0.47 g, 42%) as an off-white solid. 1H NMR (400 MHz, CDCl3); δ 79.90 (s, 1H), 7.76 (d, 1H), 7.37 (s, 2H), 7.33 (s, 1H), 7.25-7.16 (m, 4H), 7.08 (d, 2H), 5.83 (s, 2H).
