실험 절차
5-Methylindoline was prepared from 5-methylindole using the procedure described for the preparation of 5-methoxyindoline. 5-Methylindole (11 g, 0.0835 mol) in glacial acetic acid (150 mL) in a 1 L 3-necked flask was reduced at 10-15° C. with sodium cyanoborohydride (15.8 g, 0.251 mol). Extraction with ethyl acetate provided 5-methylindoline (11 g, 0.0832 mol, 99% yield) as a thick oil which was used without further purification. The structure was corroborated by NMR spectroscopy.
