4-Amino-3-iodobenzonitrile → 2-(4-methoxy-pyridin-3-yl)-1H-indole-5-carbonitrile

Participants

Reaction Steps

4-Methoxy-3-ethynyl-pyridine and 4-cyano-6-iodoaniline are processed according to the method described in Example 86 to give 2-(4-methoxy-pyridin-3-yl)-1H-indole-5-carbonitrile. 2-(4-Methoxy-pyridin-3-yl)-1H-indole-5-carbonitrile is purified by HPLC using an Xbridge Shield RP18 with a gradient of acetonitrile in 0.1% NH4OH. 1H NMR (400 MHz, DMSO-d6) δ ppm 4.04 (s, 3H), 7.14 (d, J=1.3 Hz, 1H), 7.25 (d, J=5.8 Hz, 1H), 7.47 (dd, J=8.5, 1.6 Hz, 1H), 7.61 (d, J=8.3 Hz, 1H), 8.11 (s, 1H), 8.47 (d, J=5.8 Hz, 1H), 8.91 (s, 1H), 11.91 (br. s., 1H). HRMS (ESI) m/z 250.0968 [(M+H)+ calcd for C15H12N3O: 250.0980].
