Electric Literature 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 A.7. A 20 mL vial was charged with compound A.5 (191.8 mg, 0.0006561 mol), methylene chloride (3.0 mL), a 2.0 M solution of oxalyl chloride in methylene chloride (390 muL) and DMF (10.0 muL, 0.000129 mol). The reaction mixture was stirred for 15 minutes at RT, then concentrated in vacuo and the resultant residue was taken up in acetonitrile (3.0 mL). To this solution was added a solution of compound A.6 (129 mg, 0.000656 mol) and pyridine (0.5 mL, 0.006 mol) in acetonitrile (1.5 mL). The reaction mixture was stirred at RT overnight. The solvent was removed under reduced pressure, and the residue was purified by combiflash (0-30% EtOAc/CH2Cl2) to give compound A.7 in 49% yield. MS: m/z 471 [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.
