実験手順

To a solution of (2-(((3,5-bis(trifluoromethyl)benzyl)(2-methyl-2H-tetrazol-5-yl)amino)methyl)-4-(trifluoromethyl)phenyl)(tetrahydro-2H-pyran-4-yl)methanol (20.4 mg, 0.034 mmo) in THF (0.15 mL) at 0° C. was added sodium hydride (60% dispersion in mineral oil, 4.1 mg, 0.10 mmol). The mixture was stirred at room temperature for 30 minutes, recooled to 0° C. and DMF (5 drops) was added followed by iodoethane (8 μL, 0.10 mmol). The mixture was stirred at room temperature overnight. Solvent was removed in vacuo. The residue was purified by chromatography over 12+S Biotage silica column (eluted with 0-30% ethyl acetate in hexanes) to afford the title compound (11.5 mg, 54%). 1H NMR (400 MHz, CDCl3) δ ppm 1.0 (m, 1H) 1.1 (t, J=7.1 Hz, 3H) 1.4(m, 2H) 1.7(m, 1H) 1.8(d, J=13.3 Hz, 1H) 3.2 (m, 4H) 3.9 (dd, J=11.6, 3.3 Hz, 1H) 4.0 (dd, J=11.4, 3.9 Hz, 1H) 4.2 (s, 3H) 4.2 (d, J=7.1 Hz, 1H) 4.7 (d, J=13.3 Hz, 1H) 4.7 (s, 2H) 4.9 (d, J=15.8 Hz, 1H) 7.3 (s, 1H) 7.6 (m, 2H) 7.6 (s, 2H) 7.8 (s, 1H).
