Versuchsvorschrift

To a solution of (R)-tert-butyl 3-(4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (2) (330 mg, 0.70 mmol) in DCM (10.0 mL) was added NBS (124 mg, 0.70 mmol). After the mixture was stirred at r.t. for 30 min, the reaction solution was partitioned between DCM (20.0 mL) and water (20.0 mL). The layers were separated and the organic phase was washed with brine, dried over Na2SO4 and concentrated under reduced pressure to obtain the product (R)-tert-butyl 3-(4-amino-6-bromo-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (9) (375 mg, 98% yield) as a brown solid. LC-MS (ESI): m/z (M/M+2) 550.1/552.1.
