Versuchsvorschrift
A mixture comprising 3.00 g of methyl (E)-4-(4-aminophenyl)-3-butenoate and 2.34 g of 2-methylthio-1,4-dihydro-4-oxopyrimidine was stirred at 150° to 160° C. for 20 minutes. The reaction mixture was purified by silica gel column chromatography [solvent: dichloromethane/methanol (30:1)] to obtain 1.58 g of the title compound as a light brown powder (yield: 35%).
