Procedure

To a solution of (2-chlorophenyl)-(4-chloro-2-methylsulfanylpyrimidin-5-yl)methanol (10.8 g, 35.75 mol) in toluene (150 mL) was added manganese (IV) oxide (Aldrich) (31.2 g, 10 eq). The resulting mixture was heated to reflux with stirring for a total of 2.5 hours. The reaction was then filtered hot through a 3.5 cm pad of Celite. The pad of Celite was rinsed with hot ethyl acetate, and the filtrate was concentrated to give a crude oil. Purification by Flash Column Chromatography on Silica Gel eluting with a gradient of 2%-10% ethyl acetate in hexanes gave the title compound as a yellow viscous semi-solid (5.3 g, (M+H)+=299.
