A Hinsberg`s method
B Fractional distillation method
C Hoffmann`s method

20 amine

30 amine
It does not react with benzene sulfonyl chloride.

Fractional distillation method:
Seperation by fractional distillation method is also possible if 30 amine is first removed in a constant boiling mixture with ammonia.

Hoffmanns method:
10 amine +diethyloxalatesolid oxamide
20 amine +diethyloxalateliquid oxamic ester
30 amine +diethyloxalateno reaction
