Procedure

3-Hydroxybenzamide (500 mg; 3.6 mM) was dissolved in dry acetonitrile (36 ml), and to this was added potassium carbonate (0.503 g; 3.6mmol) and 2-(bromoethyl)benzene (0.498 ml; 3.6mmol). The mixture was heated under reflux for two days. The acetonitrile was removed under reduced pressure to yield a white solid. This was dissolved in water and extracted into dichloromethane (3×30 ml). The organics were pooled, dried over magnesium sulphate, filtered and the solvent was removed under reduced pressure to yield a white solid. This was recrystallised from boiling ethyl acetate and petrol (0.459 g; 12.51%).
