Versuchsvorschrift

To a solution of 1-[3-[(2-amino-6-fluoro-pyrazolo[1,5-a]pyrimidine-3-carbonyl)amino]-5-fluoro-4-pyridyl]piperidine-4-carboxylic acid (Trifluoroacetic Acid) 29 (73 g, 124.7 mmol) in NMP (662.7 mL) was added hydrogen chloride (4M in 1,4-dioxane) (37.40 mL of 4 M, 149.6 mmol). After a few seconds a yellow precipitate formed. Mixture stirred at room temperature for 20 mins, then solid collected by filtration, washed with minimal NMP then MTBE, and dried by suction to leave pure product 30 as a light yellow solid, (59.7 g, quantitative yield). MS (ES+) 418.1.
