Potassium Carbonate → HCID 23498835, compound

Participants

Reaction Steps

Each fraction of acetic acid 2-{4-[3-(2-formyl-4,5,6,7-tetrahydro-1H-indol-3-yl)-propyl]-piperazin-1-yl}-2-oxo-ethyl ester was treated separately with potassium carbonate (3.0 eq.) in 6 ml of (methanol/ water 4/1). The two reactions were stirred at room temperature for overnight. Thin layer chromatography (dichloromethane: methanol 15:1) for both reactions showed the same spot and also LCMS showed that they have the same molecular weight. The two reactions were combined and the solvent was evaporated. The formed solid was washed with 30 ml of (dichloromethane/methanol 10/1) three times and sonicated. The liquid was collected and concentrated to give 268 mg of 3-{3-[4-(2-hydroxyacetyl)piperazin-1-yl]-propyl}-4,5,6,7-tetrahydro-1H-indole-2-carbaldehyde.
