A methylene chloride solution (99 mL) of (2-chloro-5-iodophenyl)methanol (9.01 g, 33.5 mmol) and PCC (8.67 g, 40.2 mmol) were combined and stirred at rt. After 16 h, Et2O was added and the solution stirred for 30 minutes. The solution was then filtered and the organic layer was washed with H2O (2×), NaHCO3 (3×), and brine. The organic layer was dried (Na2SO4), concentrated, and purified by Biotage chromatography (0%-20% EtOAc/hexanes) to afford 5.94 g of product (67%). 1H NMR (400 MHz, chloroform-d) δ ppm 10.38 (s, 1 H) 8.22 (d, J=2.02 Hz, 1 H) 7.83 (dd, J=8.46, 2.15 Hz, 1 H) 7.21 (d, J=8.59 Hz, 1 H).
