実験手順
Commercially available 3-nitrobenzamide is reduced with LAH under standard conditions to afford (3-nitrophenyl)methanamine, which is reacted with 4-methoxybenzylisocyanate to afford 1-(3-nitrobenzyl)-3-(4-methoxybenzyl)urea. This material is subsequently reacted with oxalyl chloride to afford 1-(3-nitrobenzyl)-3-(4-methoxybenzyl)imidazolidine-2,4,5-trione whose nitro group is reduced and oxidized to afford 1-(3-hydrazinylbenzyl)-3-(4-methoxybenzyl)imidazolidine-2,4,5-trione. This material is deprotected with TFA under standard conditions to afford the title compound I-(3-hydrazinylbenzyl)imidazolidine-2,4,5-trione.
