Potassium Carbonate → Ethyl 2-(4-(benzyloxy)-3-bromophenyl)acetate

Participants

Reaction Steps

A solution of Example 35a (2.011 mL, 16.90 mmol), and potassium carbonate (5.84 g, 42.3 mmol) in ethanol (100 mL) was refluxed for 2 hours, cooled, concentrated and the residue was partitioned with ethyl acetate and water. The organic layer was washed with brine, dried (Na2SO4), filtered and concentrated. Purification of the residue by chromatography (silica gel, 0-20% ethyl acetate in hexane) afforded the title compound (4.84 g, 98%).
