N'-[4-(1,2,2,6,6-Pentamethyl-piperidin-4-ylcarbamoyl)-phenyl]-hydrazinecarboxylic acid tert-butyl ester → 4-Hydrazino-N-(1,2,2,6,6-pentamethyl-piperidin-4-yl)-benzamide

참여 물질

반응 단계

N′-[4-(1,2,2,6,6-Pentamethyl-piperidin-4-ylcarbamoyl)-phenyl]-hydrazinecarboxylic acid tert-butyl ester was dissolved in 4M HCl in dioxane (30 ml) and left to stir for 1-2 hrs. The solution went quickly from a deep orange colour to a bright orange colour. After 1 hr reaction time, the solvent was removed under vacuum to reveal an orange oil that under a vacuum for several minutes crystalised out to give orange crystals in a sticky orange oil.
