Reaction Steps

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 10mL 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). B. 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.
