실험 절차

To a solution of 3,3-diphenylpyrrolidine (Example 17A, 0.22 g, 1.00 mmol) in dichloromethane (25 mL) under nitrogen was added 2-(3,3-bis(4-fluorophenyl)-2-oxopyrrolidin-1-yl)acetic acid (Example 58D, 0.33 g, 1.00 mmol) followed by N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.39 g, 2.00 mmol) and N,N-dimethylpyridin-4-amine (0.012 g, 0.10 mmol). The reaction mixture was stirred overnight at room temperature. The reaction was concentrated and the residue was partitioned in ethyl acetate/water (8:2). The organic layer was washed with water followed by brine, dried over magnesium sulfate, filtered, and concentrated. Silica gel chromatography eluting with 3% methanol/dichloromethane gave the title compound. 1H NMR (300 MHz, CDCl3) δ ppm 7.14-7.36 (m, 14H), 6.95-7.01 (m, 4H), 4.22 (s, 1H), 4.17 (s, 1H), 4.10 (s, 1H), 4.08 (s, 1H), 3.51-3.60 (m, 3H), 3.42 (t, J=6.7 Hz, 1H), 2.72-2.80 (m, 2H), 2.62 (t, J=6.6 Hz, 1H), 2.53 (t, J=6.8 Hz, 1H); MS (DCI+) m/z 537 (M+H)+.
