Reference of 1095823-39-4, Adding some certain compound to certain chemical reactions, such as: 1095823-39-4, name is 5-Chloro-4-(trifluoromethyl)pyridin-2-amine,molecular formula is C6H4ClF3N2, 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 1095823-39-4.
Synthesis of Compound S.7. To a solution of S.6 (205 mg, 0.64 mmol) in methylene chloride (4 mL) at rt was added oxalyl chloride (160 muL, 0.0019 mol) followed by the addition of DMF (50 muL) and stirred at RT for 1 hr. Separately a solution of A.6 (132 mg, 0.000672 mol), acetonitrile (2 ml) and pyridine (520 muL, 0.0065 mol) was stirred at RT followed by the addition of chlorotrimethylsilane (100 muL, 0.0008 mol). The acid chloride was concentrated under reduced pressure to a tan solid and redissolved in acetonitrile (2 mL). To the acid chloride solution was added the activated aniline. After 3 hr, the reaction mixture was diluted with ethyl acetate (75 mL) and washed with dilute citric acid (50 mL), aqueous sodium bicarbonate (50 mL) and water. The organic layer was dried over sodium sulfate and concentrated to a residue which was purified by to give compound S.7. MS m/z: 498.95 [M+1]+.
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. 1095823-39-4, 5-Chloro-4-(trifluoromethyl)pyridin-2-amine, other downstream synthetic routes, hurry up and to see.
