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) under ice-cooling, then the temperature was raised to room temperature, and the mixture was stirred for 1.5 hours. The reaction mixture was concentrated under reduced pressure to give 1.5 g (quantitatively) of (R)-2-pyrrolidinecarboxylic acid N-[2-(1-adamantyl)ethyl]-N-pentylamide hydrochloride as a noncrystalline solid.
