Versuchsvorschrift
(6-Fluoropyridin-3-yl)(4-(methylthio)phenyl)methanol (Example 103) (1.5304 g, 6.1387 mmol) was dissolved in DCM (60 mL) and manganese (IV) oxide (Aldrich less than micron, activated, 2.546 g, 29.28 mmol) was added. The reaction was stirred at room temperature for 90 minutes, and then more activated manganese (IV) oxide (2.736 g, 31.47 mmol) was added. The reaction was stirred overnight and then was filtered through a Celite® (diatomaceous earth) pad, which was washed with DCM. The filtrate was concentrated, and dried under high vacuum to give (6-fluoropyridin-3-yl)(4-(methylthio)phenyl)methanone (1.334 g). 1H NMR (CDCl3, 400 MHz) δ 8.64 (d, J=2.35 Hz, 1H), 8.26 (td, J=8.07 Hz, 2.45 Hz, 1H), 7.75 (d, J=8.61 Hz, 2H), 7.33 (d, J=8.41 Hz, 2H), 7.09 (dd, J=8.41 Hz, 2.54 Hz, 1H), 2.56 (s, 3H). m/z (ESI, pos. ion) 248 (M+H)+.
