The reactions of N-tosyl-O-2,4,6-trimethylbenzylhydroxylamine with primary alkyl halides yielded the protected hydroxylamines. The simultaneous cleavage of N-tosyl- and O-2,4,6-trimethylbenzyl groups with hydrogen bromide in acetic acid gave the corresponding N-monoalkylated hydroxylamines such as N-benzylhydroxylamine, 1-amino-3-hydroxyaminopropane and Dl-3-hydroxyamino-2-aminopropionic acid.
