Potassium Carbonate → HCID 22005065, compound

Participants

Reaction Steps

A mixture of the intermediate obtained in Step A (60 mg, 0.096 mmol) and potassium carbonate (5 equiv) in methanol (8 mL) and water (2 mL) was refluxed for 1.5 h. The mixture was diluted with ethyl acetate and washed with saturated aqueous sodium chloride solution. Concentration of the organic phase provided a colorless solid (60 mg, 100%) that was used in the next step without purification. 1H NMR (300 MHz, CDCl3): δ 7.4-7.2 (m, 10H), 7.11 (m, 4H), 4.90 (s, 2H), 4.39 (s, 2H), 3.34 (sept, 7.0 Hz, 1H), 2.34 (m, 2H), 1.25 (d, 7.0 Hz, 6H), 1.2 (m, 2H), 1.04 (m, 4H), 0.90 (s, 9H), 0.68 (t, 7.0 Hz, 3H).
