Electric Literature of 455-01-6, 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.455-01-6, name is 2-(3-(Trifluoromethyl)phenyl)ethanol, molecular formula is C9H9F3O, molecular weight is 190.1624, as common compound, the synthetic route is as follows.
General procedure: To a mixture of caffeic acid fine powder (1.0 g, 5.56 mmol, 1.0 equiv.),alcohol (5.56 mmol, 1.0 equiv.) in nitromethane (125 mL) was addedytterbium triflate (34.4 mg, 0.056 mmol, 0.01 equiv.). After 5 min inan ultrasonic bath the mixture without protective gas was stirred ona 120 C oil bath for a given time. The reaction mixture was cooled toroom temperature, washed with deionised water (30 mL), 2% NaHCO3(30 mL) and brine, dried over anhydrous Na2SO4 and evaporated underreduced pressure to give the crude product, which was purified on asilica gel column to give the compounds 1-5 and 8-30.
The chemical industry reduces the impact on the environment during synthesis 455-01-6, I believe this compound will play a more active role in future production and life.
