2,2-Diphenylethylamine → HCID 45275800, compound

Participants

Reaction Steps

To a solution of 2,2-diphenylethanamine (0.20 g, 1.00 mmol) in dichloromethane (20 mL) under nitrogen was added 2-(2-oxo-3,3-diphenylpyrrolidin-1-yl)acetic acid (Example 1C, 0.30 g, 1.00 mmol) followed by N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.38 g, 2.00 mmol) and N,N-dimethylpyridin-4-amine (0.61 mg, 0.005 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, 400 mL). The organic layer was washed with water followed by brine, dried over magnesium sulfate, filtered and concentrated. Silica gel chromatography eluting with ethyl acetate/hexane (1:1) gave the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 8.01 (t, J=5.6 Hz, 1H), 7.26-7.32 (m, 16H), 7.15-7.27 (m, 4H), 4.19 (t, J=7.9 Hz, 1H), 3.81 (s, 2H), 3.74 (dd, J=7.9, 5.6 Hz, 2H), 3.15 (t, J=6.4 Hz, 2H), 2.65 (t, J=6.4 Hz, 2H); MS (DCI+) m/z 475 (M+H)+, 492 (M+NH4)+.
