Versuchsvorschrift

(7-amino-2-methylpyrazolo[1,5-a]pyrimidin-6-yl)methanol (1-1) (14.1 g, 79.2 mmol) was dissolved in anhydrous CHCl3 (500 mL) and TI-IF (250 mL). Activated MnO2 (68.9 g, 792 mmol) was added to the mixture, and the mixture was stirred for 16 h. After filtration through a plug of Celite pad, the filtrate was evaporated to give 7-amino-2-methylpyrazolo[1,5-a]pyrimidine-6-carbaldehyde (1-2) as a yellowish solid.
