Versuchsvorschrift

Trifluoroacetic acid (1.2 mL, 16 mmol) was added to a solution of tert-butyl 3-{3-[1-(4-amino-3-bromo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-5-chloro-2-methoxy-6-methylphenyl}azetidine-1-carboxylate (224 mg, 0.407 mmol) in methylene chloride (2.5 mL) and stirred for 2 h at room temp. The mixture was diluted with dichloromethane and 1 N NaOH was added and stirred rapidly for a few minutes. The layers were separated and the aqueous extracted with dichloromethane. The combined organics were dried (MgSO4), filtered, and concentrated. Drying in vacuo gave 163 mg (91%) of the freebase. LCMS calculated for C18H21BrClN6O (M+H)+: m/z=451.1; Found: 451.0.
