实验步骤: To a mixture of N-(2,6-dimethylphenyl)-3-bromopropanamide (1 g, 4.5 mmol) and N-carbobenzyloxypiperazine (1.7 g, 6.8 mmol) in 10 mL of acetone was added potassium carbonate (0.93 g, 6.8 mmol). The mixture was refluxed for 24 hours. The mixture was filtered, and the solvent was removed from the filtrate under reduced pressure. The residue was purified using column chromatography, to provide N-(2,6-dimethylphenyl)-3-(4-carbobenzyloxypiperazinyl)propanamide, a compound of formula (3). The mixture was refluxed for 24 hours The mixture was filtered the solvent was removed from the filtrate under reduced pressure The residue was purified

实验步骤: To a mixture of 2,6-dimethylaniline (2 g, 16.5 mmol), diethyl ether, and aqueous saturated sodium bicarbonate (50:50 v/v) was added dropwise 3-bromopropionoyl chloride (2 g, 19.8 mm) in ether (5 mL). The mixture was allowed to stir at 0° C. for 2 hours, and at room temperature for an additional 1 hour. The organic layer was washed with 10% citric acid, dried over MgSO4, then filtered. The solvent was evaporated to afford N-(2,6-dimethylphenyl)-3-bromopropanamide, a compound of formula (1), as a white solid. at room temperature for an additional 1 hour The organic layer was washed with 10% citric acid dried over MgSO4 filtered The solvent was evaporated

To N-(2,6dimethylphenyl)-3-(4carbobenzyloxypiperanzinyl)propanamide (1.3 g) in 10 mL of methanol was added 10% Pd/C, and the mixture was hydrogenated at 30 psi for 24 hours. The mixture was filtered, and the solvent was removed from the filtrate under reduced pressure, to afford N-(2,6-dimethylphenyl)-3-piperazinylpropanamide, a compound of formula (4),which was used without further purification. C. A mixture of N-(2,6dimethylphenyl)-3-piperazinylpropanamide (0.15 g, 0.57 mmol) and 2-methyl-5-(oxiran-2-ylmethoxy)benzothiazole (0.127 g, 0.57 mmol) in 8 mL of ethanol was refluxed for 24 hours. The solvent was removed under reduced pressure, and the residue was purified using preparative TLC. The mixture was refluxed for 24 hours The mixture was filtered the solvent was removed from the filtrate under reduced pressure The residue was purified
