Procedure

To a solution of 2,4-dichloro-5-methyl-7-tosyl-pyrrolo[2,3-d]pyrimidine (0.36 g, 1 mmol) in n-butyl alcohol (3 mL) was added 6-aminoindazole (0.27 g, 2 mmol) and DIPEA (0.27 mL, 1.5 mmol) at room temperature. After heating at 90° C. for 4 h, the mixture was diluted with ethylacetate and the organic layer was sequentially washed with 1N HCl, saturated NaHCO3, and brine. The organic extract was then dried over Na2SO4 and concentrated to give a crude residue, which was purified by flash column (Hex/EtOAc=1:1) to give 2-Chloro-N-(1H-indazol-6-yl)-5-methyl-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (0.18 g).
