Procedure
A solution of sodium chlorite (9.70 g) and sodium dihydrogen orthophosphate (13.02 g) in water (50 ml) was added dropwise to a solution of ethyl 4-formyl-N-(3,4-dichlorobenzyl)indole-2-carboxylate (4.47 g) and 2-methylbut-2-ene (50 ml) in tert-butyl alcohol (100 ml) and the mixture stirred for 72 hours at ambient temperature, then concentrated in vacuo and the resulting precipitate was filtered and dried to give the product as an off-white solid (4.16 g. 89%); NMR δ(CD3SOCD3) 1.25 (t, 3H), 4.30 (q, 2H)) 5.85 (s, 2H), 6.85 (m, 1H), 7.35 (m, 1H), 7.40 (q, 1H), 7.50 (m, 1H), 7.80 (m, 3H); M/z (−) 390.1 (M−H+).
