Reaction Steps

A mixture of 79 mg of 4-methoxy-5-methyl-1H-indole-2-carboxamide (0.39 mmol), 0.19 mL of phosphorus oxychloride (2 mmol) and 1.5 mL of chloroform was refluxed for 2 hs. Then cooled solution was poured into 10 mL of water and stirred for 1 hr. After separation the organic layer was dried over sodium sulfate and concentrated. The residue was purified on silica gel column using hexane-ethyl acetate 5:1 to afford 51 mg of 4-methoxy-5-methyl-1H-indole-2-carbonitrile.
