Procedure

2-Anthracenylmethanol (46A, 1.0 g, 0.0048 mol) in CH2Cl2 (700 mL) was treated with pyridinium chlorochromate (PCC) (Aldrich, 21.56 g, 0.1 mol) and heated for 4 h. The reaction was cooled and filtered through a plug of SiO2 (500 g) using CH2Cl2 as the eluting solvent. After removal of the solvent the crude material was chromatographed on SiO2 with PhCH3 as the eluting solvent to afford 0.5 g (51%) of 2-anthracenecarbaldehyde mp 201°-202.5° (lit mp 202°-203°, P. H. Gore, J. Chem. Soc. 1616 (1959)), (C, H).
