How is (4R,5S)-5-[3,5-Bis(trifluoromethyl)phenyl]-4-methyl-1,3-oxazolidin-2-one (CAS: 875444-10-3) typically synthesized?

(4R,5S)-5-[3,5-Bis(trifluoromethyl)phenyl]-4-methyl-1,3-oxazolidin-2-one (CAS: 875444-10-3) is typically synthesized via a multistep process involving the protection of an alcohol, followed by the formation of an oxazolidinone ring. The synthesis involves the use of protecting agents such as tert-butyldimethylsilyl chloride and catalytic amounts of trifluoroacetic acid. The yield of the final product is around 65-70%, and the purity is enhanced through recrystallization.
