Adding a certain compound to certain chemical reactions, such as: 22236-10-8, name is 4-(Difluoromethoxy)aniline, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 22236-10-8, Recommanded Product: 22236-10-8
Example 1Synthesis of compound Ia-1Step 1 Compound 1 (3.44 g, 15.0 mmol) in N,N’-dimethylformamide (20 mL) at room temperature was added with 4-difluoromethoxyaniline (2.23 mL, 18.0 mmol), HOBt (2.63 g, 19.5 mmol) and EDC hydrochloride (3.45 g, 18.0 mmol). The mixture was stirred overnight at room temperature. The reaction mixture was poured into 0.05 N hydrochloride and extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium bicarbonate, and dried over magnesium sulfate, and then, the solvent was removed in vacuo. The residue was added with ethyl acetate and hexanes, and the precipitated crystals were collected by filtration to give the desired amide compound 2 (3.88 g, yield 70%).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-(Difluoromethoxy)aniline, other downstream synthetic routes, hurry up and to see.
