Procedure

A flask is charged with 2-(5-aminomethyl-pyridin-3-yl)-6-chloro-1-methyl-1H-indole-3-carbonitrile (Example 186e, 0.103 g, 0.349 mmol) and dichloromethane (2 mL). Diethylaminosulfamoyl chloride (0.072 g, 0.419 mmol) and triethylamine (0.100 mL, 0.699 mmol) are added and the reaction is stirred at room temperature overnight. The reaction mixture is concentrated in vacuo and the residue is purified by reverse phase HPLC with Xbridge Shield RP18 column and a 0.1% aqueous NH4OH in acetonitrile gradient to afford N,N-diethyl-N′-[5-(6-chloro-3-cyano-1-methyl-1H-indol-2-yl)-pyridin-3-ylmethyl]-sulfamide as a solid. 1H NMR (400 MHz, MeOD) δ ppm 1.20 (t, J=7.1 Hz, 6H), 3.30 (q, J=7.1 Hz, 4H), 3.83 (s, 3H), 4.35 (s, 2H), 7.38 (dd, J=8.6, 1.8 Hz, 1H), 7.71 (d, J=8.6 Hz, 1H), 7.77 (d, J=1.5 Hz, 1H), 8.17 (t, J=2.1 Hz, 1H), 8.79 (dd, J=3.7, 2.1 Hz, 2H). HRMS (ESI) m/z 432.1278 [(M+H)+ Calcd for C20H23ClN5O2S: 432.1261].
