Procedure

A solution of 3-((R)-2-((4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)pyrrolidin-1-yl)-3-oxopropanenitrile (141 mg, 0.30 mmol, 1.0 equiv), tert-butyl 2-methyl-1-oxopropan-2-ylcarbamate (1.12 g, 6.00 mmol, 20.0 equiv), piperidine (255 mg, 3.0 mmol, 10.0 equiv) in 1,4-dioxane (15 mL) was refluxed for 2 h. The resulting mixture was concentrated under vacuum. The residue was submitted to flash chromatography eluting with ethyl acetate to give (R)-tert-butyl (5-(2-((4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)pyrrolidin-1-yl)-4-cyano-2-methyl-5-oxopent-3-en-2-yl)carbamate 90 mg as a pale yellow solid.
