Participants

Reaction Steps

To a solution of diphenyl(piperidin-4-yl)methanol (0.27 g, 1.00 mmol) in dichloromethane (20 mL) was added 2-(2-oxo-3,3-diphenylpyrrolidin-1-yl)acetic acid (Example 1C, 0.30 g, 1.00 mmol) under nitrogen. To the reaction was added N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.38 g, 2.00 mmol) and N,N-dimethylpyridin-4-amine (6.1 mg, 0.005 mmol), and 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 separated, washed with water and then brine, dried over MgSO4, filtered and concentrated. Silica gel chromatography eluting with ethyl acetate/hexanes (1:1) gave the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 7.50-7.57 (m, 4H), 7.18-7.36 (m, 14H), 7.11-7.16 (m, 2H), 5.35 (s, 1H), 4.33-4.40 (m, 1H), 4.17 (d, J=16.6 Hz, 1H), 4.10 (d, J=15.7 Hz, 1H), 3.77-3.85 (m, 1H), 3.34 (t, J=6.7 Hz, 2H), 2.93-3.02 (m, 1H), 2.75-2.85 (m, 1H), 2.72 (t, J=6.4 Hz, 2H), 2.53-2.64 (m, 1H), 1.19-1.40 (m, 4H).
