Acetone → 8-Methoxy-6-nitro-3,4-dihydroquinolin-2(1H)-one

Participants

Reaction Steps

6-Nitro-8-hydroxy-3,4-dihydrocarbostyril (10 g) and potassium carbonate (13.3 g) were mixed with acetone (70 ml) and water (70 ml) and the mixture was refluxed with adding dropwise 12.1 g of dimethyl sulfate. After refluxing was continued for 4 hours, the reaction mixture was cooled, and crystals which precipitated were collected by filtration and washed with water to give 8.22 g of 6-nitro-8-methoxy-3,4-dihydrocarbostyril.
