Next, 4 N hydrogen chloride/dioxane (20 ml, 81 mmol) was added to (R)-1-(t-butoxycarbonyl)-2-pyrrolidinecarboxylic acid N-[2-(1-adamantyl)ethyl]-N-pentylamide (1.8 g, 4.0 mmol), and then the mixture was stirred at room temperature for 1.5 hours. The reaction mixture was concentrated under reduced pressure to give (R)-2-pyrrolidinecarboxylic acid N-[2-(1-adamantyl)ethyl]-N-pentylamide hydrochloride (1.5 g, quantitatively) as an amorphous substance.
