Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 35144-22-0, name is 4,6-Dimethyl-2-methylsulfonylpyrimidine. A new synthetic method of this compound is introduced below., Safety of 4,6-Dimethyl-2-methylsulfonylpyrimidine
Example 35 76 mg of 5-isopropyl-N-[6-(4-(4,6-dimethyl-2-pyrimidinyloxy)-2-butynyloxy)-5-(o-methoxyphenoxy)-2-methyl-4-pyrimidinyl]-2-pyridine sulfonamide was obtained as a colourless foam starting from 80 mg of 5-isopropyl-N-[6-(4-hydroxy-2-butynyloxy)-5-(o-methoxyphenoxy)-2-methyl-4-pyrimidinyl]-2-pyridine sulfonamide (Example 7d) and 75 mg of 4,6-dimethyl-2-methylsulfonylpyrimidine following the procedure given in Example 17.
