Reaction Steps

To a solution of (S)-3-(2-((4-amino-6-methyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)methyl)pyrrolidin-1-yl)-3-oxopropanenitrile (0.1 g, 0.21 mmol, 1.0 eq) in EtOH (2 mL) was added 2-(dimethylamino)-2-methylpropanal (0.06 g, 0.53 mmol, 2.5 eq) and piperidine acetate (5 mg). The resulted solution was stirred at 70° C. for 12 h, concentrated and purified by pre-HPLC to afford the title compound as a white solid (5 mg, 4% in yield). LCMS m/z 564.1 (M+H)+.
