实验步骤: A mixture of thiocytosine (0.5 g.), N-(4-chlorobut-2-ynyl)phthalimide (1.03 g.), DMF (5 ml.) and 1,5-diazabicyclo[5,4,0]undec-5-ene (0.67 g.) was stirred for 2 hours. The solution was treated with water (20 ml.) and EtOAc (10 ml.) and the insoluble solid collected to give 4-amino-2-(4-phthalimidobut-2-ynylthio)pyrimidine (1.2 g.) m.p. 197°-202° (decomp.). the insoluble solid collected

实验步骤: To a solution of 2-(4-chlorobut-2-yn-1-yl)-1H-isoindole-1,3(2H)-dione (200 mg) in acetonitrile (3 mL) was added diethylamine (188 mg) at room temperature. The reaction mixture was stirred at room temperature for 4 hr, and added to water at room temperature, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and filtered. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (112 mg). the mixture was extracted with ethyl acetate The extract was washed with saturated brine dried over anhydrous magnesium sulfate filtered The solvent was evaporated under reduced pressure the residue was purified by silica gel column chromatography (ethyl acetate/hexane)

实验步骤: To a solution of 1H-isoindole-1,3(2H)-dione (441 mg) in DMF (5 mL) were added potassium carbonate (829 mg) and 1,4-dichlorobut-2-yne (2.21 g) at room temperature. The reaction mixture was stirred at 80° C. for 5 hr. The reaction mixture was added to water at room temperature, and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and filtered. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane) to give the title compound (202 mg). the mixture was extracted with ethyl acetate The extract was washed with water and saturated brine dried over anhydrous magnesium sulfate filtered The solvent was evaporated under reduced pressure the residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane)
