Reaction Steps
A mixture of 2-cyanophenol (5.0 g, 42 mmol), cesium carbonate (27.1 g, 82.9 mmol) and 2-iodopropane (7.63 mL, 76 mmol) in acetone (80 mL) was heated at 60° C. with vigorous stirring. After 45 min, the gray brown mixture was decanted and the acetone layer was concentrated in vacuo. Water was added to dissolve the solid, and the mixture was extracted with diethyl ether (3×200 mL). The organic layers were washed with water, 1 N ammonium hydroxide and brine, and dried over anhydrous sodium sulfate. The solids were then filtered off, and the filtrate was concentrated in vacuo. Purification of the crude residue by flash chromatography (Biotage system, KP-Sil™ 32-63 μm, 60 Å silica gel) eluting with 5% ethyl acetate in hexanes yielded 2-isopropoxy-benzonitrile (6.6 g, 97%) as a colorless liquid.
