Hydrochloric Acid → Diphenylmethyl [4-(3-aminopropyl)-2,3-dioxopiperazin-1-yl]acetate hydrochloride

Participants

Reaction Steps

In 3 ml of ethyl acetate was dissolved 0.50 g of diphenylmethyl [4-[3-(tert-butoxycarbonylamino)-propyl]-2,3-dioxopiperazin-1-yl]acetate, followed by adding thereto 3.3 ml of a 1.5N solution of hydrochloric acid in dioxane, and the resulting mixture was stirred at room temperature for 3 hours. After completion of the reaction, the solvent was distilled off under reduced pressure to obtain 0.43 g of diphenylmethyl [4-(3-aminopropyl)-2,3-dioxopiperazin-1-yl]acetate hydrochloride as a yellow oil.
