实验步骤: 2.9 g of 2-tert-Butyl-4-piperazin-1-yl-6-cyclopropyl-pyrimidine (11.1 mmol), 1.8 g acetic acid 3-chloro-propyl ester (13.2 mmol), 1.38 g of triethylamine (13.7 mmol), and a spatula tip of sodium iodide were dissolved in 50 ml of dimethylformamide and stirred for 8 h at 80° C. After cooling to room temperature, the dimethylformamide was evaporated. The reaction mixture was partitioned between water and ethyl acetate. The organic layer was dried over magnesium sulfate, filtered, and the solvent was evaporated. The crude product (3.7 g) was directly used in the subsequent reaction step. After cooling to room temperature the dimethylformamide was evaporated The reaction mixture was partitioned between water and ethyl acetate The organic layer was dried over magnesium sulfate filtered the solvent was evaporated The crude product (3.7 g) was directly used in the subsequent reaction step

实验步骤: 3-Bromobenzenethiol (0.40 g) and potassium carbonate (0.44 g) were suspended in N,N-dimethylformamide (4.2 mL), 3-chloropropyl acetate (0.34 mL) was added, and the resulting mixture was stirred at 60° C. for 5 hours. The reaction mixture was partitioned between diethyl ether (40 mL) and water (10 mL). The organic layer was washed successively with water (10 mL×2) and brine (10 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was dissolved in methanol (8.5 mL), 28% sodium methoxide-methanol solution (0.08 mL) was added, and the resulting mixture was stirred at room temperature for 2 hours. The reaction mixture was concentrated under reduced pressure and the residue obtained was purified by column chromatography on silica gel (eluent: hexane/ethyl acetate=3/1) to give the title compound (0.49 g).
