Reaction Steps

To a solution 209 mg of potassium 3-amino-3H-quinazolin-4-one-2-thiolate in 5 ml of dimethylformamide, 141 mg of methyl iodide was added, and stirred for 20 minutes at room temperature. Water was added to the solution, followed by extraction with ethyl acetate and drying over anhydrous magnesium sulfate. Distilling the solvent off under reduced pressure, 161 mg (86%) of 3-amino-2-methylthio-3H-quinazolin-4-one was obtained.
