Reaction Steps

Stir a solution of 5-(6-Amino-1-isopropyl-1H-indol-3-yl)-1-ethyl-1H-pyrazole-3-carbonitrile (0.126 g, 0.393 mmol), pyridine (0.062 g, 0.786 mmol) and methanesulfonyl chloride (0.068 g, 0.590 mmol) in methylene chloride (3 mL) at room temperature for 2.5 h. After this time, Purify the reaction directly by chromatography (silica, methylene chloride to 1:9 ethyl acetate/methylene chloride) then freeze-dried from acetonitrile/water to afford N-[3-(5-Cyano-2-ethyl-2H-pyrazol-3-yl)-1-isopropyl-1H-indol-6-yl]-methanesulfonamide (0.132 g, 90%) as alight purple solid: mp 144-145° C.; 1H NMR (500 MHz, DMSO-d0.6 δ0.60 (s, 1H), 7.84 (s, 1H), 7.50 (d, J=9.0 Hz, 1H), 7.45 (d, J=2.0 Hz, 1H), 7.11 (s, 1H), 7.04 (dd, J=8.5, 1.5 Hz, 1H), 4.73 (m, 1H), 4.27 (q, J=7.0 Hz, 21H), 2.96 (s, 3H), 1.52 (d, J=6.5 Hz, 6H), 1.35 (t, J=7.0 Hz, 3H) LCMS (Method 4)>99%, 6.96 min, m/z 372 [M+H]+.
