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. 80936-82-9, name is 4-(Methoxymethyl)aniline, A new synthetic method of this compound is introduced below., Quality Control of 4-(Methoxymethyl)aniline
Example 82 Synthesis of 4-amino-1-(4,4-difluorocyclohexyl)-N-(4-(methoxymethyl)phenyl)-1H-pyrazolo[3,4-d]pyrimidine-3-carboxamide 33 mg of methyl-4-amino-1-(4,4-difluorocyclohexyl)-1H-pyrazolo[3,4-d]pyrimidine-3-carboxylate obtained in step 2 of Reference Example 10 was dissolved in 2 mL of methanol. 0.05 mL of a 5M aqueous sodium hydroxide solution was added thereto at room temperature, and the mixture was stirred at 60 C. for 1 hour. After cooling, 0.2 mL of a 5M aqueous hydrochloric acid solution was added, and the mixture was concentrated under reduced pressure. The obtained solid was suspended in 2 mL of DMF, and 17 mg of 4-(methoxymethyl)aniline, 60 mg of HATU, and 0.055 mL of N,N-diisopropylethylamine were added thereto at room temperature, followed by stirring at the same temperature for 1 hour. The reaction solution was diluted with ethyl acetate, and washed with water and a saturated aqueous sodium chloride solution. The obtained organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated. The obtained residue was suspended in methanol, and filtered, followed by drying at 60 C. under reduced pressure, thereby obtaining 29 mg of the title compound.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
