实验步骤: A solution of 1-(4-(trifluoromethyl)benzyl)piperazine (0.046 g, 0.188 mmol), 2-(2-oxo-3,3-diphenylpiperidin-1-yl)acetic acid (Example 68E, 0.053 g, 0.171 mmol) and N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.049 g, 0.257 mmol) in dichloromethane (0.5 mL) was stirred at room temperature. After stirring overnight, 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 0.4% to 4.5% methanol/dichloromethane over 20 minutes (flow=30 mL/minute). 1H NMR (300 MHz, CDCl3) δ ppm 7.56-7.60 (m, 2H), 7.42-7.46 (m, 2H), 7.27-7.33 (m, 8H), 7.18-7.25 (m, 2H), 4.23 (s, 2H), 3.66 (t, J=4.7 Hz, 2H), 3.55 (s, 2H), 3.50 (t, J=6.5 Hz, 2H), 3.44-3.49 (m, 2H), 2.62-2.66 (m, 2H), 2.35-2.50 (m, 4H), 1.79-1.88 (m, 2H); MS (ESI+) m/z 536 (M+H)+. the title compound was eluted over 20 minutes
