Reaction Steps

25 g (180 mmol) of (R)-phenylglycinol and then 4 g (16 mmol) of pyridinium para-toluenesulfonate are added to a solution of 25.8 g (230 mmol) of trifluoroacetone in 200 mL of toluene in a three-necked flask on which is mounted Dean-Stark apparatus. The mixture obtained is then heated at 110° C. for 5 hours. After cooling, the reaction mixture is concentrated under reduced pressure. The residue obtained is purified by filtration on silica (eluent: dichloromethane) to give 35.10 g of (R)-2-methyl-4-phenyl-2-trifluoromethyloxazolidine in the form of a colorless liquid, the characteristics of which are as follows:
