Cesium carbonate → HCID 57126714, compound

Participants

Reaction Steps

A solution of 18 (36 mg, 0.076 mmol) and cesium carbonate (50 mg, 0.153 mmol) in acetonitrile (100 mL) was treated with 2,2,2-trifluoroethyliodide (21.3 mg, 0.101 mmol) at room temperature. The resulting mixture was stirred at room temperature overnight. The mixture was diluted with dichloromethane and water and the aqueous layer was extracted with two additional portions of dichloromethane. The combined organic extracts were concentrated under reduced pressure and purified by PCTLC (SiO2, 4 mm, 1% NH4OEt-1% NH4OEt-10% EtOH-90% CHCl3) to afford the title compound (49) which was converted to the hydrochloride salt after treatment with EtOAc/HCl.
