Related Products of 1245506-61-9, 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.1245506-61-9, name is 2-Chloro-5-methoxy-4-methylpyrimidine, molecular formula is C6H7ClN2O, molecular weight is 158.59, as common compound, the synthetic route is as follows.
(2) 2-Chloro-4-methylpyrimidin-5-ol (Prep 1-2)A dichloromethane solution (50 ml) of the compound Prep 1-1 (6.6 g) was added dropwise to a dichloromethane solution (1.0 M: 100 ml) of boron tribromide, and the obtained mixture was then stirred at room temperature for 4 days. Thereafter, methanol was added to the reaction mixture, and a 5 N sodium hydroxide aqueous solution was then added to the reaction solution for neutralization. Liquid separation and extraction were carried out successively using chloroform and ethyl acetate at a pH value of approximately pH 2 to 3. The organic layer was dried over magnesium sulfate, and the solvent was then concentrated under reduced pressure. Diethyl ether was added to the obtained residue to solidify it, and the solidified product was collected by filtration and was then dried, so as to obtain the title compound.1H-NMR (400 MHz, DMSO-d6) delta (ppm): 2.32 (s, 3H), 8.09 (s, 1H), 10.61 (s, 1H).
The chemical industry reduces the impact on the environment during synthesis 1245506-61-9, I believe this compound will play a more active role in future production and life.
