Hydrochloric Acid → N-((2-(2,6-Dioxopiperidin-3-YL)-1-oxoisoindolin-5-YL)methyl)piperazine-1-carboxamide

Participants

Reaction Steps

A mixture of tert-butyl 4-((2-(2,6-dioxopiperidin-3-yl)-1-oxoisoindolin-5-yl)methylcarbamoyl)piperazine-1-carboxylate (0.49 g, 1.0 mmol) in methylene chloride (100 mL) is treated with HCl (5 mL of a 2N solution in diethyl ether), and stirred at ambient temperature for 48 hours. The mixture is evaporated under vacuum, and triturated in ethyl acetate (10 mL), filtered, and dried under vacuum.
