Light yellow solid | [Uses]
4-Amino-6-chloropyrimidin-5-ylamine is a chlorinated diaminopyrimidine used in the preparation of various bioactive choloropurine derivatives.
| [Synthesis]
Step 1: 4,6-Dichloropyrimidin-5-amine (1.64 g, 10 mmol) was suspended in 5 mL of concentrated hydrochloric acid. The suspension was transferred to a sealed tube, ammonia solution was added and the reaction was stirred at 100 °C overnight. Upon completion of the reaction, the solid product was collected by filtration and dried under vacuum to afford the target compound 6-chloropyrimidine-4,5-diamine as a yellow solid (1.2 g, 83% yield).LC-MS analysis showed m/z 145 ([M+H]+). | [References]
