Procedure

The mixture of 3-(6-bromo-pyridin-2-yl)-6-chloro-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-d]pyrimidine (from Example 31 supra) (2.65 g, 6.01 mmol), tert-butyl (1r,4r)-4-aminocyclohexylcarbamate (1.53 g, 7.14 mmol) and Et3N (1.4 mL, 9.7 mmol) in IPA (60 mL) was heated at reflux for 16 hours. After cooling to room temperature, the reaction mixture was filtered and solid dried to give {4-[3-(6-bromo-pyridin-2-yl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino]-cyclohexyl}-carbamic acid tert-butyl ester as white powder. (Yield 3.3 g, 89%).
