Procedure

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 (150.mg, 0.32 mmol), piperidine (0.03 mL, 0.32 mmol) and 2-methyl-2-(1-piperidyl)propanal (74.08 mg, 0.48 mmol) in ethanol (8 mL) was heated in a sealed tube at 90° C. for 16 hrs. The solution was cooled and concentrated. The residue was dissolved in ethyl acetate and washed with 5% citric acid and brine and then dried (MgSO4), filtered and concentrated. The crude material was purified by Isolera (10 grams column at 0% to 6% MeOH/ethyl acetate) to obtain 15 mg (8%) of the title compound. MS (pos. ion) m/z: 609 (M+1).
