Versuchsvorschrift

To a solution of 3-[(2R)-2-[[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]methyl]pyrrolidin-1-yl]-3-oxo-propanenitrile (100 mg, 0.2100 mmol) dissolved in methanol (4 mL) and DCM (4 mL) was added piperidine (0.1 mL, 0.8500 mmol) and tert-butyl N-(1-formylcyclopropyl)carbamate (58.9 mg, 0.3200 mmol). The reaction was heated to reflux for 6 hrs and then cooled and concentrated. The residue was and dissolved in ethyl acetate (50 mL) and washed with water (50 mL) and then brine. The organic layer was dried (MgSO4), filtered and concentrated. The residue was purified by Isolera (1%-8% MeOH/DCM) to provide 39 mg (13% yield) of tert-butyl N-[1-[3-[(2R)-2-[[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]methyl]pyrrolidin-1-yl]-2-cyano-3-oxo-prop-1-enyl]cyclopropyl]carbamate.
