To a microwave vial 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 (139.3 mg, 0.30 mmol), piperidine (0.04 mL, 0.35 mmol), 2-methyl-2-(1-piperidyl)propanal (68.8 mg, 0.4400 mmol) and toluene (3 mL). The vial was heated under microwave conditions at 160° C. for 3 hrs. The reaction was cooled and concentrated, then dissolved in ethyl acetate (30 mL) and washed with 2M HCl. The aqueous layer was basified to pH˜7.5 with sat. NaHCO3 and washed with ethyl acetate. The organic layer was dried (MgSO4), filtered and concentrated and the crude material was purified by Isolera (1%-10% MeOH/ethyl acetate) to obtain 32 mg (18%) of the title compound. MS (pos. ion) m/z: 609 (M+1).
