Reaction Steps

To 2-(4-methoxy-benzoyl)-cyclobutanecarboxylic acid (10.28 g, 43.88 mmol) was added 48% hydrogen bromide in water (50 mL) and acetic acid (50 mL). After overnight stirring at 120° C., the reaction was concentrated, stirred with ethanol a few times, and the product was purified using a Single Step column (7:3 hexanes:ethyl acetate) to obtain 7.70 g (71%); MS m/z 247 (M−H)
