Procedure

To a solution of 4-(5-(1-amino-2,2,2-trifluoroethyl)pyridin-3-yl)-2-methylbenzonitrile (322 mg, 1.105 mmol) in CH2Cl2 (5.5 mL) at 0° C. was added triethylamine (462 μl, 3.32 mmol) and ethanesulfonyl chloride (115 μl, 1.216 mmol). The mixture was stirred for 16 h at room temperature. The mixture was quenched with saturated NaHCO3 and extracted with EtOAc two times, dried over magnesium sulfate, filtered, concentrated. The residue was purified via Biotage (10-50% EtOAc/heptane; SNAP25 column) giving the title compound (67 mg, 16%). LC-MS (M+1) 384.1. 1H NMR (400 MHz, MeOD) δ ppm 1.28 (t, J=7.33 Hz, 3H) 2.63 (s, 3H) 2.96-3.19 (m, 2H) 5.47 (q, J=7.89 Hz, 1H) 7.66-7.72 (m, 1H) 7.76-7.79 (m, 1H) 7.81 (d, J=8.02 Hz, 1H) 8.24-8.43 (m, 1H) 8.76 (d, J=2.27 Hz, 1H) 8.93 (d, J=2.21 Hz, 1H).
