Sodium Carbonate → 4-(3-Hydroxy-4-methyl-phenylamino)-7-methoxy-quinoline-3-carbonitrile

Participants

Reaction Steps

To a suspension of 200 mg (0.91 mmol) of 4-chloro-7-methoxy-3-quinolinecarbonitrile and 135.5 mg (1.10 mmol) of 5-amino-o-cresol in 10 mL of 2-ethoxy ethanol was added 105.6 mg (0.91 mmol) of pyridine hydrochloride. The resulting reaction mixture was refluxed for 1 hr, and then the solvent was removed to give a residue. To the residue was added about 30 mL of water and neutralized to pH 7-8 by addition of diluted sodium carbonate solution. The precipitate was collected by filtration and washed with water and ether. After drying in vacuo, this afforded 277 mg (99%) of the product as a yellow solid, m.p.>250° C., mass (electrospray, m/e): M+H 305.9.
