Is it possible to convert hydroxamic acid to (NH-OH) to acetamide (NH2)?

Question

Is it possible to convert the NH-OH group in 2-benzhydrylsulfinylethane hydroxamic acid aka "Adrafinil" to Benzhydrylsulphinyl acetamide aka "Modafinil", swapping the NH-OH for NH2? If so, how would one go about it?

Answer 1

A Google search on "reduction of hydroxamic acids" turned up an article called "Reduction of hydroxamic acids to the corresponding amides catalyzed by rabbit blood". This could be a good starting point...

Answer 2

You would hydrogenate it:

-NH-OH +H2 -> -NH2 + H2O

What conditions or catalyst this might require, I have no idea. There is also the question of what else would happen to what is a complex molecule..........
