To a solution of methyl 4-cyclobutylbenzoate (168.1, 2.00 g, 10.5 mmol, 1.00 equiv) in acetic acid (30 mL) were carefully added sodium periodate (1.00 g, 4.68 mmol, 0.50 equiv), iodine (3.00 g, 11.8 mmol, 1.10 equiv) and sulfuric acid (0.15 g, 0.15 equiv). The resulting mixture was stirred overnight at 100° C. After cooling to room temperature, the reaction was then quenched by carefully adding 30 mL of Na2S2O3 (aq., sat.) and the resulting mixture was extracted with 3×20 mL of ethyl acetate. The combined organic layers were washed with 3×20 mL of brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to yield 1.50 g (45%) of the title compound as a yellow oil.
