Reaction Steps

Methyl N-(3,4-Dichlorobenzyl)-5-acetylaminoindole-2-carboxylate (88 mg) and lithium iodide (300 mg) were dissolved in pyridine and heated at reflux for 8 hours, then cooled to room temperature and poured into 2M HCl and extracted with diethyl ether. Combined organic extracts were dried (MgSO4) and concentrated in vacuo to give an oil which was purified by column chromatography using DCM-2% methanol as eluent to give the desired end product as a white solid (19 mg, 22%), mp 245-246°; NMR δ(CD3SOCD3) 2.02 (s, 3H), 5.82 (s, 2H), 6.90 (d, 1H), 7.20-7.55 (m, 5H), 8.02 (s, 1H), 9.83 (s, 1H); M/z(+) 377 (MH+), 278.
