4-Amino-m-cresol → 4-(4-Hydroxy-2-methyl-phenylamino)-6,7-dimethoxy-quinoline-3-carbonitrile

Participants

Reaction Steps

Using an analogous procedure to that described in Example 286, 248.7 mg (1 mmol) of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile in 15 mL of 2-ethoxyethanol and in the presence of 115.6 mg (1 mmol) of pyridine hydrochloride was reacted with 147.8 mg (1.2 mmol) of 4-amino-m-cresol to give 304.6 mg (90.9%) of the product as a salmon solid, m.p.>250° C., mass (electrospray, m/e): M+H 335.9
