Abstract
"A process for obtaining D (-) threo-1-p-nitrophenyl-2-dichloroacetamido-1,3-propanediol" essentially characterized in that it consists of saturating the D, L-threo-p-toluenesulfinate-2-amino-1-p-nitrophenyl-1 , 3-propanediol with the addition of D (-) threo p tooluensulfinate-2-amino-1-p-nitrophenyl-1,3-propanediol in aqueous and aqueous alcoholic medium of glycols, heating and cooling the solution obtained at temperatures between 75 [deg.] C. and 10 [deg.] C., whereby D (-) threo p-toluenesulfinate is isolated in an amount greater than that added, and D (-) threo p-toluenesulfinate-2-amino-1-p-nitrophenyl-1,3-propanediol is then reacted with Methyl dicloracetate in aqueous medium in the presence of alcohols and other miscible solvents in water.
