| | 2,6-Dichloropurine Usage And Synthesis |
| Chemical Properties | white to light yellow crystal powder | | Uses | Suzuki-Miyaura cross-coupling between halopurines and arylboronic acids in water-acetonitrile.1 | | Uses | 2,6-Dichloropurine is used in the synthesis of 2,6-diamino-substituted purine derivatives as potential cardiomyogenesis inducing agents. | | Synthesis Reference(s) | Journal of the American Chemical Society, 80, p. 404, 1958 DOI: 10.1021/ja01535a040 | | Purification Methods | It can be recrystallised from 150 parts of boiling H2O and dried at 100o to constant weight. It is soluble in EtOAc. The HgCl2 salt separates from EtOH solution. UV: max 275nm ( 8.9K) at pH 1; and 280nm ( 8.5K) at pH 11 [Elion & Hitchings J Am Chem Soc 78 3508 1956, Schaeffer & Thomas J Am Chem Soc 80 3738 1958, Beaman & Robins J Appl Chem (London) 12 432 1962, Montgomery J Am Chem Soc 78 1928 1956].
