Procedure

A mixture of (R)-tert-butyl 3-(4-amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (1) (2.0 g, 4.66 mmol), 4-phenoxyphenylboronic acid (1.3 g, 6.06 mmol), Pd(dppf)Cl2 (190 mg, 0.23 mmol) and Na2CO3 (1.9 g, 14.0 mmol) in DME (35.0 mL) and H2O (15.0 mL) was heated at 90° C. under N2 atmosphere overnight. After cooled down to r. t., the reaction mixture was diluted with water (50.0 mL) and DCM (50.0 mL). The layers were separated and the aqueous phase was extracted with DCM (25 mL×1). 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, 0-80% ethyl acetate in petroleum ether (“PE”) with DCM (1:1)) to afford (R)-tert-butyl-3-(4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (2) (1.3 g, 60% yield) as a yellow solid. LC-MS (ESI): (M+1) 472.1.
