Reaction Steps

A suspension of N-(5-chloro-2-hydroxyphenyl)urea (53 mg, 0.28 mmol), cesium carbonate (92 mg, 0.28 mmol) and epibromohydrine (49 mg, 0.36 mmol) in dry DMF (0.6 mL) was stirred at room temperature for 24 hours. The mixture was then partitioned between ethyl acetate and water. The organic phase was washed with water three times, dried and concentrated to a solid residue. This crude product was recrystallized (ethyl ether and heptane to afford the subtitle compound (18 mg, 26.5%).
