Versuchsvorschrift

A solution of (R)-5-(2-(2-(2-(tert-butoxycarbonylamino)ethylamino)-5-fluoropyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (31 mg, 0.064 mmol) in HCl (4 N dioxane, 798 μL) and TFA (50% DCM, 2 mL) was stirred at ambient temperature for 1 hour before it was concentrated and dried under high vacuum to yield to give the desired product as off-white solid, which was used in the next step directly without further purification, assuming quantitative conversion. MS (apci) m/z=386.1 (M+H).
