The resulting suspension was poured into water (10 mL) and stirred for 30 min. The resulting precipitate was collected by filtration, and the residue was washed with water (10 mL), dried at the pump for ca. 1 hour. The solid residue was dissolved in acetone and adsorbed onto silica and purified by flash chromatography (0-10% MeOH in EtOAc) to afford 5-{1-[(6-chloro-2-pyridinyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (99.8 mg, 53.7% yield) as a beige solid.
