4-Toluenesulfonyl chloride → p-Toluenesulfonate

Participants

Reaction Steps

In an operation carried out in a manner similar to that described in Example 1, p-toluene-sulfonyl chloride is added portionwise to a cooled solution of 2-phenyl-3-(t-butylamino)-5-(hydroxymethyl)oxazolidine in pyridine while the temperature is maintained below 25° C. to obtain a tosylate of the 2-hydroxymethyloxazolidine.
