Potassium Carbonate → HCID 86622677, compound

Participants

Reaction Steps

Title compound 362 (400 mg, 1.69 mmol), ethyl 6-bromohexanoate (0.3 mL, 1.69 mmol) and potassium carbonate (584 mg, 4.23 mmol) were mixed in DMF (20 mL) and the reaction mixture was heated to 80 oC for 24 hours. The DMF was removed and the residue was partitioned between water and ethyl acetate. The 2 layers were split and the aqueous layer was extracted with 2 other portions of ethyl acetate. The combined organic layers were washed with brine, dried, filtered and evaporated. The crude product was purified by flash chromatography (2:1 to 1:2, hexanes:ethyl acetate) to afford title compound 363 (400 mg, 63%) as a clear oil.
