Procedure

A solution of (S)-2-(4-amino-5-iodo-pyrrolo[2,3-d]pyrimidin-7-ylmethyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (500.00 mg, 1.13 mmol, 1.0 eq), 4-phenoxyphenyl-boronic acid (240.00 mg, 1.13 mmol, 1.0 eq), Pd(PPh3)4 (100.00 mg), and Na2CO3 (300.00 mg, 2.83 mmol, 2.5 eq) in Dioxane/H2O (40/10 ml) was stirred at 90° C. for 4 h. The reaction mixture was concentrated and purified by Pre-TLC to afford (S)-2-[4-amino-5-(4-phenoxy-phenyl)-pyrrolo[2,3-d]pyrimidin-7-ylmethyl]-pyrrolidine-1-carboxylic acid tert-butyl ester (500 mg, 91% in yield).
