Procedure

To a mixture of 2-chloro-N-cyclopropyl-5-iodo-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (0.3 g, 0.61 mmol), Pd(PPh3)2Cl2 (0.086 g, 0.122 mmol) and pyridine-4-ylboronic acid (0.165 g, 1.342 mmol) in dioxane (3 mL) was added a solution of Na2CO3 (0.2 g, 1.83 mmol) in water (1.5 mL). After degassing, the mixture was heated at 100° C. for 1.5 h. The mixture was purified by flash column chromatography (Hexane/EtOAc=1:1) to give 2-chloro-N-cyclopropyl-5-(pyridin-4-yl)-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (0.241 g).
