A solution of (4-(trifluoromethyl)phenyl)methanamine (0.033 g, 0.186 mmol), 2-(2-oxo-3,3-diphenylpyrrolidin-1-yl)acetic acid (Example 1C, 0.050 g, 0.169 mmol) and N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.049 g, 0.254 mmol) in dichloromethane (0.5 mL) was stirred at room temperature. After stirring overnight, the reaction was loaded directly onto a SF15-12 column (Analogix®, Burlington, Wis.), and the title compound was eluted using a gradient of 5% to 100% ethyl acetate/hexanes over 20 minutes (flow=30 mL/minute). 1H NMR (300 MHz, CDCl3) δ ppm 7.50-7.54 (m, 2H), 7.17-7.33 (m, 12H), 6.39 (t, J=6.1 Hz, 1H), 4.34 (d, J=6.1 Hz, 2H), 4.07 (s, 2H), 3.51 (t, J=6.5 Hz, 2H), 2.81 (t, J=6.5 Hz, 2H); MS (ESI−) m/z 451 (M−H)−.
