In 2018,Bucevicius, Jonas; Turks, Maris; Tumkevicius, Sigitas published 《Easy Access to Isomeric 7-Deazapurine-1,2,3-Triazole Conjugates via S N Ar and CuAAC Reactions of 2,6-Diazido-7-deazapurines》.Synlett published the findings.Synthetic Route of C6H3Cl2N3 The information in the text is summarized as follows:
A simple and efficient synthesis of isomeric 7-deazapurine-1,2,3-triazole conjugates, e.g. I, with amino substituents from readily available 9-alkyl-2,6-diazido-7-deazapurines has been developed using consecutive CuAAC and regioselective nucleophilic substitution reactions of azido and 1,2,3-triazole groups with amines. The experimental part of the paper was very detailed, including the reaction process of 2,4-Dichloro-7H-pyrrolo[2,3-d]pyrimidine(cas: 90213-66-4Synthetic Route of C6H3Cl2N3)
2,4-Dichloro-7H-pyrrolo[2,3-d]pyrimidine(cas: 90213-66-4) belongs to pyrimidine. The pyrimidine ring system has wide occurrence in nature as substituted and ring fused compounds and derivatives, including the nucleotides cytosine, thymine and uracil, thiamine (vitamin B1) and alloxan.
