Procedure

A suspension of (R)-tert-butyl 3-(4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (2) (1.0 g, 2.1 mmol) in MeCN (30.0 mL) was cooled to 0° C. with ice bath. Selectfluor (1.5 g, 4.2 mmol) was added to the reaction mixture in one portion. After addition, the ice-water bath was removed, and the stifling was continued for 1 hr at r. t. The reaction mixture was susequently partitioned between water (30 mL) and DCM (50 mL). The layers were separated and the aqueous phase was extracted with DCM (10 mL×3). Combined organic phases were washed with brine, dried over Na2SO4 and concentrated under reduced pressure to obtain the crude product which was purified by column chromatographic (silica gel, 0 to 50% ethyl acetate in DCM) to afford (R)-tert-butyl 3-(4-amino-6-fluoro-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (3) (175 mg, 17% yield) as a yellow solid. LC-MS (ESI): (M+1) 490.1.
