实验步骤: To 1-(2,6-dichlorobenzyl)piperazine (0.045 g, 0.183 mmol), 2-(1H-benzo[d][1,2,3]triazol-1-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (0.069 g, 0.183 mmol) and 2-(2-oxo-3,3-diphenylpyrrolidin-1-yl)acetic acid (Example 1C, 0.054 g, 0.183 mmol) in dichloromethane (0.5 mL) was added diisopropylethylamine (0.048 mL, 0.274 mmol), and the reaction mixture was stirred at room temperature. After stirring overnight, thin layer chromatography (hexanes/ethyl acetate 1:1) indicated formation of the product. The reaction was loaded directly onto a SF15-12 silica gel column (Analogix®, Burlington, Wis.), and the title compound was eluted using a gradient of 5% to 75% ethyl acetate/hexanes over 20 minutes (flow=30 mL/minute). 1H NMR (300 MHz, CDCl3) δ ppm 7.10-7.38 (m, 13H), 4.19 (s, 2H), 3.71 (s, 2H), 3.48-3.59 (m, 4H), 3.33-3.40 (m, 2H), 2.81 (t, J=6.5 Hz, 2H), 2.50-2.58 (m, 2H), 2.41-2.49 (m, 2H); MS (DCI+) m/z 522.1 (M+H)+. After stirring overnight the title compound was eluted over 20 minutes
