Application of 3680-69-1, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 3680-69-1, name is 4-Chloro-7H-pyrrolo[2,3-d]pyrimidine, molecular formula is C6H4ClN3, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Step 1To a solution of 4-chloro-7H-pyrro]o[2,3-d]pyrimidine (8.0 g , 52.32 mmol, 1.0 eq) in DMF (40 raL), NiS ( 15.7g , 57.55 mmol, 1.1 eq) was added at 0 C. The reaction mixture was stirred overnight at room temperature. Water (40 rnL) was added to the reaction mixture, extracted with EtOAc. The organic layer was dried over Na2S04 and concentrated under vacuum to give 4-chloro-5-iodo-7H-pyrrolo[2,3-d]pyrimidine (14.6 g, 100 % in yield).
According to the analysis of related databases, 3680-69-1, the application of this compound in the production field has become more and more popular.
