Reaction Steps

A mixture of 1-(5-bromothiazole-2-yl)-3,5-dimethyl piperazine (21.5 g), bromo acetic acid methyl ester (8.8 mL), potassium carbonate (12.9 g) and dimethylformamide (150 mL) was stirred at 60° C. for 2.5 hours. To the reaction solution was added water and extracted with ethyl acetate. The organic layer was washed with water and brine, and dried over magnesium sulphate. The solvent was evaporated under reduced pressure. The residue was purified by column chromatograph on silica gel to give the title compound (20.1 g). Yield: 74%.
