Procedure

A solution of 4-hydroxyphenylacetone (4.5 g, 30 mmol) and potassium carbonate (4.14 g, 3.0 eq.) in 50 mL of acetone was stirred under N2 as 1-bromo-3-chloro-propane was added dropwise. The reaction was heated to 80° C. overnight. The mixture was then filtered through celite, washed with acetone and concentrated to afford 1-[4-(3-chloro-propoxy)phenyl]propan-2-one (6.3 g, 93% yield): MS m/z 227 (M+H).
