Reaction Steps

Treat a solution of 4-[2-(2-chloro-5-fluoro-pyrimidin-4-yl)-benzo[b]thiophen-7-yl]-pyridin-3-ol (100 mg, 0.28 mmol) and cesium carbonate (100 mg, 0.28 mmol) in dimethylformamide (1 mL) with ethyl iodide (44 mg, 0.28 mmol). Stir the mixture at room temperature for 12 hours. Dilute the mixture with ethyl acetate and wash the solution with three portions of water, one portion of saturated aqueous sodium chloride, dry over sodium sulfate, filter, and concentrate in vacuo. Purify the crude product by column chromatography on 12 g silica gel eluting with a gradient of dichloromethane to ethyl acetate to give the title compound (48 mg, 45%) as a brown solid.
