A referee suggested that the determination of the relative proportion of 2 and 3 by HPLC using UV detection is an estimate unless it has been proven that both diastereoisomers have the same UV response. The fact that the enantiomeric ratios of the free primary amines are equal to the corresponding 2:3 diastereomeric ratios determined by HPLC indicates that the latter technique is appropriate for determining the diastereomeric ratio of this kind of sulfinamides.
