実験手順
To the solution of (S)-tert-butyl 2-((4-chloro-6-methyl-7H-pyrrolo[2,3-d]pyrimidin-7-yl)methyl)pyrrolidine-1-carboxylate (1.0 g, 2.86 mmol, 1.0 eq) in DMF (20 mL), NIS (0.675 g, 3.00 mmol, 1.05 eq) was added at 0° C. The resulted mixture was stirred and warmed to RT for 12 h. Solvent was removed and purified by column chromatography to afford (S)-tert-butyl 2-((4-chloro-5-iodo-6-methyl-7H-pyrrolo[2,3-d]pyrimidin-7-yl)methyl)pyrrolidine-1-carboxylate as white solid (1.0 g, 77% in yield) which was converted to the title compound as described in Example 30 above. LCMS m/z 519.1 (M+H)+.
