| Hazard Information | Back Directory | [Uses]
5-Amino-4,6-dichloro-2-methylpyrimidine is a useful research chemical for organic synthesis and other chemical and pharmacological processes. | [Application]
5-Amino-4,6-dichloro-2-methylpyrimidine can be used as an intermediate in medical synthesis, such as the preparation of mosonidine. Mosonidine is a widely used antihypertensive drug. | [Synthesis]
GENERAL METHOD: 10% Pd/C catalyst (0.05 g) was added to a solution of 4,6-dichloro-2-methyl-5-nitropyrimidine (4.48 mmol) in ethyl acetate (EA, 20 mL) in a Parr hydrogenation reactor. Subsequently, the air in the reactor was replaced with nitrogen three times and the hydrogenation reaction was carried out at room temperature and at atmospheric pressure. Upon completion of the reaction, the Pd/C catalyst was removed by diatomaceous earth filtration and the filtrate was concentrated to afford the intermediate 2-methyl-4,6-dichloro-5-aminopyrimidine (11a). The product was a light-colored solid, yield: 84.0%; mass spectrum (ESI) m/z: 177.94 [M + H]+. | [References]
