Reaction Steps

A mixture of (R)-tert-butyl 3-(4-amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)piperidine-1-carboxylate (250 mg, 0.56 mmol), 4-phenoxyphenylboronic acid (133 mg, 0.62 mmol), Pd(PPh3)4 (100 mg) and Na2CO3 (150 mg, 1.41 mmol) in dioxane/H2O (40/10 ml) was stirred at 100° C. for 4 h. The reaction mixture was concentrated and purified by Pre-TLC to obtain (R)-tert-butyl 3-(4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)piperidine-1-carboxylate (150 mg, 55% in yield).
