Reaction Steps

1H-indole-7-carbaldehyde (1 g, 6.9 mmol) in EtOH (30 mL), hydroxylamine (527 mg, 7.6 mmol) in water (10 mL) was added followed by 50% NaOH (1.38 g in 1.38 mL water) was added. After refluxing for 2 h, ethanol was removed under reduced pressure. Resultant slurry was extracted with ethylacetate. Organic layer was washed with water, brine and dried. Crude residue was column chromatographed on a silica gel eluting with (30% EtOAc/hexanes) to afford (Z)-1H-indole-7-carbaldehyde oxime in 80% yield.
