6-methoxy-8-nitro-quinolin6-methoxy-8-nitroquinoline - Reference Information
| Use | the product can be used as an intermediate of antimalarial primaquine phosphate. |
| production method | is obtained by cyclization of 4-methoxy-2-nitroaniline. Glycerol was added to the reaction pot, and sulfuric acid was added at a temperature below 70 ° C., followed by addition of 4-methoxy-2-nitroaniline. After incubation at 75-80 °c, an aqueous solution of potassium iodide and iodine was added and the temperature was raised to 125 °c until the end point of the reaction was reached. It is diluted with ice water, neutralized to pH 3.5 with sodium hydroxide solution at below 35 °c, filtered and washed with water to pH 5 to give 6-methoxy-8-nitroquinoline. The yield was 90%. |
