A series of pyrrolo[2,3-d]pyrimidine derivatives were prepared and optimized for cytotoxic activities against FLT3-ITD mutant cancer cells. Among them, compound 9u possessed nanomolar FLT3 inhibitory activities and subnanomolar inhibitory activities against MV4-11 and Molm-13 cells. It also showed excellent inhibitory activities in FLT3-ITD-D835V and FLT3-ITD-F691L cells which were resistant to quizartinib. Furthermore, 9u exhibited over 40-fold selectivity toward FLT3 relative to c-Kit kinase, which might reduce myelosuppression toxicity. Cellular assays demonstrated that 9u inhibited phosphorylated FLT3 and downstream signaling factors and also induced cell cycle arrest in the G0/G1 stage and apoptosis in MV4-11 and Molm-13 cells. Oral administration of 9u at 10 mg/kg could achieve rapid tumor extinction in the MV4-11 xenograft model and significantly inhibit the tumor growth in the MOLM-13 xenograft model with a tumor growth inhibitory rate of 96% without obvious toxicity. Additionally, 9u demonstrated high bioavailability (F = 59.5%) and suitable eliminated half-life time (T1/2 = 2.06 h), suggesting that 9u may be a potent candidate for treating acute myelogenous leukemia.

The invention relates to a synthesis method of 4 -lopyrrolopyrimidine compound, which comprises the following steps: mixing 4 -hydroxypyrrolopyrimidine, phosphorus oxychloride and organic base in a temperature range &at;timetimewise and removing excess ethanol to obtain 3 - 7-amino-4 -iodopyrrolopyrimidine; thirdly, dissolving the product 4 -amino-4 -methyl pyrrolopyrimidine in DMF at room temperature and then drying and concentrating 4 -aminopyrrolopyridine. 4 -aminopyrimidine is dissolved in dichloromethane and then subjected to a heat preservation reaction to get -5 -aminopyrrolopyrimidine; and the mixture is dried to remove the solid insoluble matter and is dried and concentrated to yield 12 hours-aminopyrroyrimidine after the heat preservation reaction is carried out; and the solvent is evaporated to remove the solid insoluble matter and is dried and concentrated to remove the solid insoluble matter 4 -5 -7.
