Versuchsvorschrift
To a solution of (2-ethyl-pyrazolo[1,5-a]pyridin-3-yl)-methanol (9.67 g, 54.9 mmol) in tetrahydrofuran (500 mL) was added MnO2 (23.88 g, 274.5 mmol, 85%, dried in oven at 120° C. for 16 h) and stirred at the reflux temperature for 1.5 h. The reaction mixture was filtered through a Celite pad, and concentrated under reduced pressure to give 9.4 g (98%) of product, which was used without further purification.
