[5-(2-morpholin-4-yl-ethoxy)-1H-indol-2-yl]-methanol → 5-(2-morpholin-4-yl-ethoxy)-1H-indole-2-carbaldehyde

Participants

Reaction Steps

Manganese (IV) oxide (3.2 g, 36 mmol) was added to [5-(2-morpholin-4-yl-ethoxy)-1H-indol-2-yl]-methanol (0.7 g) in dichloromethane (150 mL). The mixture was stirred at room temperature for 16 hours. The precipitate was filtered off and the filtrate was concentrated. The residue was recrystallized from ethyl acetate and hexane to give 0.18 g of 5-(2-morpholin-4-yl-ethoxy)-1H-indole-2-carbaldehyde.
