Reaction Steps

To a solution of 4-ethyl-3-(3-methoxy-propoxy)-benzoic acid (6.44 g, 27.03 mmol) in CH2Cl2 (150 mL) at −78° C. is slowly added BBr3 (9 mL, 93.41 mmol). The reaction mixture is allowed to reach RT and stirred for 3 hours, then poured into ice/water and filtrated to afford the title product as a white solid. TLC, Rf (CH2Cl2/MeOH 95:5)=0.2.
