Procedure

The (2S,4S)-1-tert-butyl 2-methyl 4-(4-amino-5-((3,5-dimethoxyphenyl)ethynyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1,2-dicarboxylate (393.8 mg) obtained in Example 66 (Step 6) was dissolved in methanol (6 ml). After cooling to 0° C., 4N aqueous sodium hydroxide (3 ml) was added thereto. The reaction suspension was stirred at room temperature for 3 hours. 5N hydrochloric acid was added to the reaction mixture to a pH of 5, and ethyl acetate and water were added to separate the organic layer. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure to obtain the title compound as a light-yellow solid (280 mg). Physical properties: m/z[M+H]+ 508.3
