Procedure

To a mixture of 2-chloro-N-methyl-5-iodo-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (0.05 g, 0.11 mmol), Pd(PPh3)2Cl2 (0.015 g, 0.022 mmol) and pyridine-4-ylboronic acid (0.03 g, 0.24 mmol) in p-dioxane (0.7 mL) was added a solution of Na2CO3 (0.035 g, 0.33 mmol) in water (0.3 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-methyl-5-(pyridin-4-yl)-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (0.02 g).
