(3-fluoro-5-iodophenyl)methanol (9.79 g, 35.0 mmol) was dissolved in DCM (94 mL) and then silica gel (18.0 g) was added. To the mixture at room temperature was added PCC (18.3 g, 45.0 mmol) portion-wise and the mixture agitated at room temperature for 1 h and followed by TLC. After 1 h, TLC indicated complete conversion of the SM to a non-polar (presumably aldehyde). The reaction mixture was filtered over 1-inch plug of silica pad and eluted with 30% Ether in DCM (200 mL). The filtrate was concentrated in vacuo to afford the crude product, which was taken to the next step without further purification.
