1H-Indazol-6-amine → 7-Ethoxy-4-(indazol-6-ylamino)-6-methoxy-quinoline-3-carbonitrile

Participants

Reaction Steps

A mixture of 500 mg (1.90 mmol) 4-chloro-7-ethoxy-6-methoxy-quinoline-3-carbonitrile, 30 ml ethanol, and 304 mg (2.28 mmol) 6-aminoindazole was heated to reflux under N2. Removed heat at 4 hours and made basic with saturated sodium bicarbonate. Stripped solvents, slurried residue with hexane, collected solids and dried. Washed with water and dried in vacuo, giving 546 mg of tan solid: mass spectrum (electrospray m/e): M+H=359.9.
