実験手順

N-Methylmorpholine (60 μL) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (94 mg) were added to a solution of trans-4-(N-tert-butoxycarbonylglycylamino)-N-tert-butoxycarbonyl-L-proline (Compound D103 (B), 200 mg), 4-(2-chloro-5-methylphenoxy)piperidine (117 mg) and, 1-hydroxybenzotriazole (70 mg) in tetrahydrofuran (6 mL) and N,N-dimethylformamide (2 mL) at room temperature. After stirring at room temperature for 14 hr, the reaction mixture was partitioned between ethyl acetate and 1 N hydrochloric acid. The organic layer was washed with saturated sodium hydrogen carbonate and brine. After drying over anhydrous sodium sulfate, the organic layer was evaporated in vacuo. The residue was washed with hexane to give the titled compound (309 mg) as a white foam: 1H NMR (400 MHz, CDCl3) δ 1.43-1.46 (18H), 1.89 (br s, 4H), 2.16 (br s, 2H), 2.32 (s, 3H), 3.34-3.60 (m, 3H), 3.70-4.00 (m, 5H), 4.49 (br s, 0.5H), 4.62 (m, 2H), 4.79 (br s, 0.5H), 5.11 (br s, 1H), 6.34 (br s, 1H), 6.77 (m, 2H), and 7.24 (m, 1H). Anal. Calcd for C29H43Cl1N4O7: C, 58.53; H, 7.28; N, 9.41; Cl, 5.96. Found: C, 58.21; H, 7.35; N, 9.25; Cl, 6.03; IR (KBr) 3319, 2978, 2933, 1699, 1666, 1404, 1252, 1165, 1061 cm−1; mass spectrum (EI+) m/e 594 (M).
