Procedure

To a suspension of Selenium dioxide (0.333 g, 3.00 mmol) in 1,4-Dioxane (8.0 mL) was added a solution of 4-Bromo-6-(4-tert-butyl-cyclohexyloxy)-2-methyl-quinoline (0.469 g, 1.25 mmol) in 1,4-Dioxane (4.0 mL). The mixture was sealed and was heated at 50° C. in an oil bath. After 4 d, the reaction was filtered through Celite and washed with dioxane. The solvent was evaporated and the residue was purified on silica gel column using 0-25% ethyl acetate in hexanes as eluent. Isolated was the product (Rf=0.68 in 3:1 hexanes/ethyl acetate) in 362 mg yield, 74%. ESI (M+H+): 390.10/392.10.
