Related Products of 918538-05-3,Some common heterocyclic compound, 918538-05-3, name is 2,4-Dichloropyrrolo[2,1-f][1,2,4]triazine, molecular formula is C6H3Cl2N3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A mixture of 2,4-dichloropyrrolo[1,2-f][1,2,4]triazine (150 mg, 0.8 mmol), 2-oxa-6-azaspiro[3.3]heptane (103mg, 1.04 mmol) and K2C03 (221 mg, 1.6 mmol) in DMF (4.5 mL) was stirred at room temperature for 2h. TLC showed the starting material was completely consumed and DCM (10 mL) was added to the mixture, and the mixture was washed with water (5 mL) and brine. The organic layer was dried over anhydrous Na2SO4 and concentrated in vacuo to give compound 35(160 mg, 8 1%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2,4-Dichloropyrrolo[2,1-f][1,2,4]triazine, its application will become more common.
