Reaction Steps

To a mixture of 2,4-dichloro-5-iodo-7-tosyl-7H-pyrrolo[2,3-d]pyrimidine (0.414 g, 0.88 mmol) in nBuOH (1.5 mL) was added cyclopropylamine (0.0674 mL, 1.06 mmol) and DIPEA (0.188 mL, 1.06 mmol). After stirring at ambient temperature for 15 h, the resulting precipitate was collected by filtration to give 2-chloro-N-cyclopropyl-5-iodo-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (0.3 g).
