Reaction Steps
A solution of 4-bromo-2-hydroxy-benzonitrile (0.89 g, 4.45 mmol) in THF (50 mL) and 1-butanol (2.0 mL) is slowly added to NaH (0.356 g, 8.90 mmol). The mixture is stirred at room temperature for one hour and quenched with water (10 mL). The mixture is concentrated, and the residue is extracted with ethyl acetate (20 mL×2). The combined organic layers are dried over sodium sulfate and concentrated to provide 4-bromo-2-butoxy-benzonitrile (0.65 g, 57%). 1H NMR (400 MHz, CDCl3): δ 7.37-7.34 (d, 1H), 7.11-7.08 (d, 1H), 7.08 (s, 1H), 4.04-4.01 (t, 2H), 1.80 (tt, 2H), 1.50 (tt, 2H), 0.95 (t, 3H).
