Reaktionsschritte

To a mixture of 2,4-dichloro-5-iodo-7-tosyl-7H-pyrrolo[2,3-d]pyrimidine (1.5 g, 3.2 mmol) in n-butyl alcohol (12 mL) was added 6-aminoindazole (0.47 g, 3.52 mol) and DIPEA (0.86 mL, 4.80 mmol). After heating at 45° C. for 15 h, the mixture was cooled to room temperature, and the resulting precipitates were collected by filtration to give 2-chloro-N-(1H-indazol-6-yl)-5-iodo-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (1.1 g).
