Procedure

3-hydroxybenzamide (0.5 g 3.6 mmol) was dissolved in dry acetonitrile (50 ml). To this was added potassium carbonate (0.503 g; 3.6 mmol) and cinnamyl chloride (0.5 ml; 3.6 mmol). This was left to reflux for 3.5 hours. The acetonitrile was removed under reduced pressure yielding a white sold which was dissolved in water (80 ml). The organics were extracted in dichloromethane (3×30 ml), dried over magnesium sulphate, filtered and the solvent removed under reduced pressure leaving a white solid. The solid was recrystallised from ethyl acetate and petrol (45%).
