Participants

Reaction Steps

To a mixture of 8.8 g of 8,9-dimethoxy-1,2,3-triazino[4',5':4,5]thieno[2,3-b]quinolin-4(3H)-one and 12 g of potassium carbonate in 50 ml of dimethylformamide at 75° C. is added 6 ml of methyl iodide. Stirring at this temperature is continued for 3 hours. The mixture is then diluted with water and the precipitate which forms is separated by filtration to give 8,9-dimethoxy-3-methyl-1,2,3-triazino[4',5':4,5]thieno[2,3-b]quinolin-4(3H)-one.
