Procedure

A flask is charged with 2-(5-aminomethyl-pyridin-3-yl)-1-methyl-1H-indole-3-carbonitrile (130 mg, 0.5 mmol), DBU (304 mg, 2.0 mmol) and DCE (15 mL), and isopropylsulfonyl chloride (142 mg, 1.0 mmol) is added. The mixture is stirred at room temperature for 1 h and concentrated in vacuo. The residue is purified by silica gel flash chromatography (dichloromethane-methanol, 1:0 to 97:3) to give propane-2-sulfonic acid [5-(3-cyano-1-methyl-1H-indol-2-yl)-pyridin-3-ylmethyl]-amide. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.24 (d, J=6.8 Hz, 6H), 3.18-3.26 (m, 1H), 3.79 (s, 3H), 4.37 (d, J=6.1 Hz, 2H), 7.34-7.38 (m, 1H), 7.41-7.46 (m, 1H), 7.70-7.79 (m, 3H), 8.08 (t, J=2.0 Hz, 1H), 8.77 (d, J=2.3 Hz, 1H), 8.81 (d, J=2.3 Hz, 1H). HRMS (ESI) m/z 369.1389 [(M+H)+ Calcd for C19H21N4O2S: 369.1385].
