Piperidine → 2-[(2S)-2-[[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]methyl]pyrrolidine-1-carbonyl]-4-methyl-4-morpholino-pent-2-enenitrile

온도

105 °C

To a sealed tube was added 3-[(2S)-2-[[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]methyl]pyrrolidin-1-yl]-3-oxo-propanenitrile (900 mg, 1.91 mmol), ethanol (12 mL), piperidine (0.23 mL, 2.29 mmol) and 2-methyl-2-morpholino-propanal (0.49 mL, 2.86 mmol). The tube was sealed and heated to 105° C. for 24 hrs. The mixture was then cooled, concentrated and then dissolved in ethyl acetate (100 mL) and washed with 5% citric acid (100 ml) and then brine. The organic layer was dried (MgSO4), filtered and concentrated. The crude material was purified by Isolera (column size 100 g. Solvent system 4%-8% MeOH/EtOAc) to obtain 245 mg (21% yield) of the title compound. MS (pos. ion) m/z: 611 (M+1).
