Patent US5288907 (http://l2.espacenet.com/dips/viewer?PN=US5288907&CY=gb&LG=en&DB=EPD)
Various N-alkylhydroxylamines (such as N-methylhydroxylamine and N-isopropylhydroxylamine) made by low-pressure catalytic hydrogenation of the corresponding nitroalkanes.
Perhaps the N-OH-PEA´s could be made with this method??
Catalytic hydrogenation freak
