Application of 105806-13-1, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.105806-13-1, name is 4,6-Dichloro-5-fluoro-2-methylpyrimidine, molecular formula is C5H3Cl2FN2, molecular weight is 181, as common compound, the synthetic route is as follows.
(Step d) Preparation of 2-Methyl-4-hydroxy-5-fluoro-6-chloropyrimidine To a mixture of water (3 mL) and concentrated sulfuric acid (7 mL) was added 1.81 g (10 mmol) of 2-methyl-4,6-dichloro-5-fluoropyrimidine. The reaction mixture was stirred for 3 hours and then poured onto ice. The mixture was saturated with sodium chloride and extracted with ethyl acetate. The organic extracts were combined, dried (MgSO4), filtered, and concentrated in vacuo to give crude product (1.4 g, 86%), m.p. 214-216 C. This product was used in subsequent reactions without further purification. 1 H NMR (60 MHz, CDCl3) delta 2.42 (s, 3H); IR (Nujol) 1650, 1585, 1450 cm-1.
The chemical industry reduces the impact on the environment during synthesis 105806-13-1, I believe this compound will play a more active role in future production and life.
