Versuchsvorschrift

A mixture of 80 mg of potassium 3-amino-5,6-dimethyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidine-2-thiolate, which was prepared from ethyl 2-amino-4,5-dimethylthiophene-3-carboxylate; 104 mg of 2-[4-(3-chloropropyl)piperazin-1-yl]quinoline as prepared in the Step 1-1-B; and 5 ml of ethanol, was heated under reflux for 4.5 hours. After cooling off the reaction mixture, chloroform was added, followed by washing with saturated brine. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified on silica gel column chromatography (chloroform:methanol=100: 1) to provide 72 mg (50%) of 3-amino-5,6-dimethyl-2-[3-(4-quinolin-2-ylpiperazin-1-yl)-propylthio]-3H-thieno[2,3-d]pyrimidin-4-one.
