Reference of 722-92-9, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.722-92-9, name is 2-(4-Aminophenyl)-1,1,1,3,3,3-hexafluoropropan-2-ol, molecular formula is C9H7F6NO, molecular weight is 259.15, as common compound, the synthetic route is as follows.
i) To a solution of 2-(5-bromopyridin-2-yl)acetic acid (500 mg) in DCM (4 mL) were added 2-(4-aminophenyl)-1,1,1,3,3,3-hexafluoro-propan-2-ol (625 mg), EDCl (476 mg) and DMAP (57 mg). The reaction mixture was stirredat RT for 1 hour, poured into water, filtered on a water repellent filter cartridge and concentrated under reducedpressure. The residue was purified by column chromatography on silica gel, using 10percent EtOAc in heptane as theeluent, followed by trituration with ether/pentane to obtain 820 mg of the expected compound. MS(ES+) m/z 456.9[M+H]+.
Statistics shows that 722-92-9 is playing an increasingly important role. we look forward to future research findings about 2-(4-Aminophenyl)-1,1,1,3,3,3-hexafluoropropan-2-ol.
