反応手順

To a solution of 1-(5-chloropyridin-2-yl)-1-(3-fluoro-5-(trifluoromethyl)phenyl)-2-phenylethanamine (0.02 g, 0.051 mmol) in dichloroethane (0.5 mL) in a two dram vial was added 4-methyl-1H-imidazole-5-carbaldehyde (6 mg, 0.051 mmol), followed by a drop of acetic acid. The reaction mixture was shaken for 20 minutes at room temperature and then NaBH(OAc)3 was added (12 mg, 0.056 mmol). The reaction was stirred at room temperature overnight. The solvents were removed and the residue was purified by preparative HPLC (phenominex C18 column, 21×100 mm, 5μ) using MeOH/H2O (with 0.1% TFA) to give 1-(5-chloropyridin-2-yl)-1-(3-fluoro-5-(trifluoromethyl)phenyl)-N-((4-methyl-1H-imidazol-5-yl)methyl)-2-phenylethanamine as a white solid (23.4 mg, 76% yield). LCMS: 3.6 min [M+1] 489.2 (4 min gradient, MeOH/H2O 0.1% TFA); 1H NMR (400 MHz, CDCl3) δ ppm 2.27 (s, 3 H), 3.45-3.52 (m, 1 H), 3.88-3.99 (m, 2 H), 4.01-4.07 (m, 1 H), 6.64 (d, J=7.09 Hz, 2 H), 7.02 (d, J=8.56 Hz, 1 H), 7.10 (t, J=7.46 Hz, 2 H), 7.18 (t, J=7.46 Hz, 1 H), 7.49 (d, J=7.58 Hz, 1 H), 7.61 (d, J=9.54 Hz, 1 H), 7.69 (s, 1 H), 7.76 (dd, J=8.56, 2.45 Hz, 1 H), 8.28 (s, 1 H), 8.60 (d, J=1.96 Hz, 1 H).
