Participants

Reaction Steps

A total of 1.76 g of 2-indolemethanol was dissolved in dry CH2Cl2 (20 mL) at room temperature and stirred overnight with MnO2 (2.1 g, 24 mmol). The mixture was filtered through Celite, the filtrate was evaporated under reduced pressure, and the product was purified by flash chromatography (CH2Cl2). Yield: 1.31 g (75%), 1H NMR (CDCl3): δ7.1-7.5 (m, 4H), 7.76 (d, 1H, J=7.8 Hz), 9.41 (br s, 1H), 9.86 (s, 1H).MS EI): m/z 145 (M+).
