Potassium Carbonate → HCID 86722066, compound

Participants

Reaction Steps

K2CO3 (2.76 g, 20 mmol, 2 eq.) was added to a solution of 4a (4.50 g, 10.36 mmol, 1 eq.) in degassed MeOH (200 mL). The suspension was stirred at room temperature for 30 min. before concentration. The residue was partitioned between EtOAc (200 mL) and brine (200 mL). The EtOAc layer was separated and washed further with brine (100 mL), dried over MgSO4, filtered and concentrated. The crude product was purified by flash chromatography (0-50%, EtOAc in heptane) to afford 5a as a colorless oil (3.60 g, 96%).
