Definition ChEBI: 6-chloro-2,4-pyrimidinediamine (4-Chloro-2,6-diaminopyrimidine) is a member of pyrimidines and an organohalogen compound.
Synthesis 2,4-Diamino-6-hydroxypyrimidine (1.00 g, 7.93 mmol) was added to POCl3 (9 mL) and stirred at 97 ℃ for 17 h. The reaction solution was added to ice water slowly and then stirred at 90 C for 1 h. The pH of this solution was adjusted to 8 with NaOH, and then it was extracted with EtOAC (150 mL 3). The combined organic layers were dried with Na2SO4, filtered, and concentrated to give white solid 4-Chloro-2,6-diaminopyrimidine 0.97 g, yielding 85%.
