Reaction Steps

To a solution of 4-(5-(1-aminocyclopropyl)pyridin-3-yl)-2-chlorobenzonitrile (70 mg, 0.26 mmol) in DCM (3 mL) at room temperature was added TEA (0.109 mL, 0.779 mmol) and EtSO2Cl (74 μL, 0.779 mmol) dropwise, and the mixture was stirred at room temperature for 1 h. The mixture was concentrated in vacuo, re-dissolved in DMF (3 mL) and filtered. The filtrate was purified by Xbridge Phenyl followed by Xbridge C18 eluting with 20-80% ACN-water gradient to give N-(1-(5-(3-chloro-4-cyanophenyl)pyridin-3-yl)cyclopropyl)ethanesulfonamide. HRMS: (ESI) m/z 362.0712 [(M+H)+ Calcd for C17H16ClN3O2S 362.0725]. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.28 (t, J=7.3 Hz, 3H), 1.32-1.38 (m, 2H), 1.49-1.54 (m, 2H), 2.90 (q, J=7.4 Hz, 2H), 7.60 (dd, J=8.1, 1.8 Hz, 1H), 7.74 (d, J=1.8 Hz, 1H), 7.79 (d, J=8.1 Hz, 1H), 8.01 (t, J=2.3 Hz, 1H), 8.67 (d, J=2.3 Hz, 1H), 8.72 (d, J=2.3 Hz, 1H).
