A mixture of (2,3-dimethylphenyl)(1-trityl-IH-imidazol-5-yl)methanol, (Intermediate 6) (2.4 g, 7.4 mmol) in CH2Cl2 (60 mL) was treated with manganese (IV) oxide, activated (commercially available from Aldrich): MnO2 (2.8 g, 32.3 mmol) at room temperature. The mixture was heated at 60° C. for 2 hours. The mixture was then cooled to room temperature and filtered through celite and the solvent was removed under vacuum. The residue was purified by MPLC with 3 to 5% MeOH:CH2Cl2 to give (2,3-dimethylphenyl)(I-trityl-IH-imidazol-5-yl)methanone, (Intermediate 7), 1.48 g, (62%).
