Next, a 4 N solution of hydrogen chloride in ethyl acetate (55 ml, 0.22 mol) was added to 2-[N′(t-butoxycarbonyl)-N-propylamino]acetic acid N-(1-adamantyl)amide (7.68 g, 21.9 mmol), and the mixture was stirred at room temperature for one hour. The resulting crystals were filtered off with ethyl acetate and washed with ethyl acetate to give 5.97 g (95%) of the titled compound as colorless crystals.
