Sodium Carbonate → 4-(3-Hydroxy-4-methyl-phenylamino)-6,7,8-trimethoxy-quinoline-3-carbonitrile

Participants

Reaction Steps

A mixture of 0.279 g of 4-chloro-6,7,8-trimethoxy-quinoline-3-carbonitrile, 0.148 g of 5-amino-o-cresol, and 10 ml of ethoxyethanol was stirred under nitrogen, at reflux temperature for 30 minutes. The mixture was cooled and added to 100 ml of water. To this mixture was added sodium carbonate to pH 9. The product was collected, washed with water, and dried to give 0.279 g of 4-(3-hydroxy-4-methyl-phenylamino)-6,7,8-trimethoxy-quinoline-3-carbonitrile as a solid, mp 200° C. (decomposed); mass spectrum (EI, m/e): M 365.1356.
