1-Pyrrolidineethanamine → 6-chloro-1-methyl-2-{5-[(2-pyrrolidin-1-yl-ethylamino)-methyl]-pyridin-3-yl}-1H-indole-3-carbonitrile

Participants

Reaction Steps

6-Chloro-2-(5-formyl-pyridin-3-yl)-1-methyl-1H-indole-3-carbonitrile (Example 126) and 2-pyrrolidin-1-yl-ethylamine are processed according to the method described in Example 170 to give 6-chloro-1-methyl-2-{5-[(2-pyrrolidin-1-yl-ethylamino)-methyl]-pyridin-3-yl}-1H-indole-3-carbonitrile. The free base is taken up in 4M HCl in dioxane, concentrated in vacuo, dissolved in water and lyophilized to give the HCl salt. 1H NMR (400 MHz, DMSO-d6) δ ppm (HCl salt) 1.83-1.93 (m, 2H), 2.04 (br. s., 2H), 3.06 (br. s., 2H), 3.50 (br. s., 2H), 3.54-3.60 (m, 2H), 3.66 (br. s., 2H), 3.84 (s, 3H), 4.43 (br. s., 2H), 7.39 (dd, J=8.6, 1.8 Hz, 1H), 7.75 (d, J=8.3 Hz, 1H), 8.01 (d, J=1.5 Hz, 1H), 8.43 (t, J=2.0 Hz, 1H), 8.94 (d, J=2.0 Hz, 1H), 8.99 (d, J=2.0 Hz, 1H), 9.97 (br. s., 2H), 10.89 (br. s., 1H).
