875444-08-9, (4S,5R)-5-(3,5-Bis(trifluoromethyl)phenyl)-4-methyloxazolidin-2-one is a oxazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A solution of ethyl [trans-4-( {ethyl [2-(hydroxymethyl)-4-(trifluoromethyl)phenyl] amino}methyl)cyclohexyl]acetate (Step B; 60 mg; 0.149 mmol) in toluene (1 mL) was added dropwise to a stirred solution of thionyl chloride (12.3 muL; 0.169 mmol) in toluene (300 muL) at 0C. The reaction stirred at room temperature for 1.5 h. Pyridine (27 mL) was added and the reaction was partitioned between toluene (10 mL) and H2O (10 mL). The aqueous layer was re-extracted with toluene (10 mL) and the combined organic layers were washed with brine (10 mL), dried (Na2SO4), filtered and concentrated in vacuo. The residue was dissolved in DMF (1 mL) and (45,5i?)-5-[3,5- bis(trifluoromethyl)phenyl]-4-methyl-l,3-oxazolidin-2-one (intermediate 17; 56 mg; 0.179 mmol) and potassium terf-butoxide (23.5 mg; 0.209 mmol) were added successively. The reaction stirred for 72 h and was quenched with sat. NH4Cl. The reaction was partitioned between sat. NH4Cl (10 mL) and
As the paragraph descriping shows that 875444-08-9 is playing an increasingly important role.
