Versuchsvorschrift

(5-Bromo-pyridin-3-yl)-methanol (1.13 g, 6.00 mmol) was dissolved in CHCI3 (40 mL) and treated with MnO2 (3.60 g). The reaction mixture was heated at reflux temperature for 3 h. The hot reaction mixture was filtered through a pad of diatomaceous earth and the filtrate was concentrated to yield the title compound (0.570 g, 51%).
