Versuchsvorschrift

A solution of 4 N hydrochloric acid in 1,4-dioxane (8 mL) was added to a solution of 1-[trans-4-(N-tert-butoxycarbonylglycylamino)-N-tert-butoxycarbonyl-L-prolyl]-4-(2-chloro-5-methylphenoxy)piperidine (C, 280 mg) in 1,4-dioxane (8 mL) at room temperature. After stirring at room temperature for 20 min, the reaction mixture was evaporated in vacuo. The residue was washed with ether to give the titled compound (142 mg) as a white powder: 1H NMR (400 MHz, D2O) δ 1.90-2.01 (4H), 2.32 (s, 3H), 2.43 (m, 1H), 2.61 (br s, 1H), 3.49 (br t, 2H), 3.67 (br s, 1H), 3.79 (m, 4H), 3.85 (s, 2H), 4.58 (br s, 1H), 5.02 (m, 1H), 6.91 (d, J=8.0 Hz, 1H), 7.09 (s, 1H), and 7.35 (d, J=8.0 Hz, 1H); mass spectrum (EI+) m/e 394 (M).
