Reaction Steps

To a mixture of (S)-(4-(trifluoromethyl)phenyl)(3-(trifluoromethyl)-pyridin-2-yl)methanamine (Intermediate 1) (0.0610 g, 0.190 mmol) and DIPEA (0.066 mL, 0.381 mmol) in MeCN (1 mL) was added ethyl carbonochloridate (0.027 mL, 0.286 mmol). The mixture was then stirred at rt overnight. The mixture was diluted with saturated aqueous NaHCO3 and extracted with DCM. The organic phase was dried over Na2SO4 and concentrated in vacuo. The resulting product was purified by silica gel chromatography: 5-50% EtOAc-hexanes to give the title compound as a colorless oil. 1H NMR (400 MHz, CDCl3) δ ppm 8.83 (d, J=4.30 Hz, 1H), 7.99 (d, J=7.24 Hz, 1H), 7.46-7.60 (m, 4H), 7.40 (dd, J=7.73, 4.79 Hz, 1H), 6.54 (d, J=7.43 Hz, 1H), 6.41 (d, J=8.22 Hz, 1H), 4.11 (q, J=7.17 Hz, 2H), 1.17-1.30 (m, 3H). MS (ESI pos. ion) m/z: 393.0 (M+H).
