Procedure

A mixture of 2-chloro-N-(1H-indazol-6-yl)-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (400 mg, 0.912 mmol), 4-(methylthio)aniline (0.227 mL, 1.83 mmol) and trimethylsilyl chloride (TMSCl) (0.231 mL, 1.83 mmol) in n-butyl alcohol (8 mL) was heated at 116° C. for 72 h. Water and ethyl acetate were then added. The organic phase was separated, washed with 5% NaHCO3, dried over Na2SO4, and concentrated in vacuo. The residue was dissolved in CH3CN (20 mL), and water was added to induced precipitation. The solid was collected by filtration to give N4-(1H-indazol-6-yl)-N2-(4-(methylthio)phenyl)-7-tosyl-7H-pyrrolo[2,3-d]pyrimidine-2,4-diamine (225 mg). The filtrate was also purified by HPLC to give another portion of the desired product (127 mg).
