実験手順
Triethylamine (130 μL), 1-hydroxybenzotriazole (59 mg), and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (89 mg) were added to a solution of the 4-phenylbenzylamine trifluoroacetate (B, 126 mg) and trans-4-(N-tert-butoxycarbonylglycylamino)-N-tert-butoxycarbonyl-L-proline (Compound D103 (B), 150 mg) in dichloromethane (10 mL) at 0° C. The mixture was stirred at room temperature for 16 hr and concentrated in vacuo. The residue was diluted with ethyl acetate and washed with 1 N hydrochloric acid, water, saturated sodium hydrogen carbonate, and brine. The organic layer was dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by silica gel column chromatography (chloroform then chloroform:methanol=99:1 to 98:2, v/v) to give the title compound (178 mg) as a colorless foam:1H NMR (400 MHz, CDCl3) δ 1.45 (s, 18H), 1,67 (s, 2H), 2.01 (brs, 1H), 2.64 (br s, 1H), 3.27 (br s, 1H), 3.68-3.81 (m, 3H), 4.23-4.70 (m, 3H), 5.17 (br s, 1H), 6.43 (br s, 1H), 7.32-7.36 (m, 3H), 7.44 (t, J=7.6 Hz, 2H), and 7.53-7.57 (m, 4H).
