Oxalyl chloride → 2-Oxo-(5-phenoxy-1H-indol-3-yl)acetyl chloride

Participants

Reaction Steps

Combine 5-phenoxy-indole (1.57 g, 7.5 mmol) and anhydrous ether (35 mL) and add oxalyl chloride (1.07 g, 8.25 mmol) in 8 mL ether. A precipitate forms. Stir the reaction over night. Collect the precipitate, dry in vacuo, to give the title compound: 1H NMR (300 MHz, DMSO-d6) 6.99–7.15 (m, 4H), 7.37–7.42 (m, 2H), 7.60 (d, 1H, J=8.7 Hz), 7.75 (d, 1H, J=2.4 Hz), 8.47 (d, 1H, J=3.2 Hz), 12.49, (br, 1H).
