Conditions

Temperature
120 °C

Procedure

The mixture of 2 g of 2-amino-3-cyano-4-hydroxy-6-(4-methylpiperazino)quinoline and 4 mL of phosphoryl chloride is stirred at 120° C. for 4 hours. The cooled reaction mixture is poured onto 40 g of ice, the pH of the mixture is adjusted to 8 with 10% NaOH solution, and the precipitated material is filtered off. After drying 1.5 g of the title compound is obtained, m.p.: 189° C.
