実験手順
Four and five tenths (4.5) grams of 2,5-diphenyl oxazolidine was dissolved in 50 ml. of methylene chloride and 5 g. of 2,3-dibromopropionyl chloride was added and the mixture stirred in an ice bath, while 2.1 g. of triethylamine was added dropwise. After standing for about 30 minutes, the mixture was washed with water, separated and dried over magnesium sulfate and stripped under vacuum. There was obtained a yield of 7.1 g. of an oil, the title compound, ND30 =1.5734.
