Reaction Steps

2-Bromoethyl methyl ether (0.94 mL) was added dropwise to a suspension of piperazine-4-carboxylic acid tert-butyl ester (1.87 g) and potassium carbonate (1.38 g) in N,N-dimethylformamide (20 mL) at room temperature, and the resultant mixture was stirred at 60° C. for 24 hours. The reaction mixture was partitioned by use of ice-water and ethyl acetate. The organic layer was sequentially washed with water and saturated brine, and then dried over magnesium sulfate anhydrate, followed by filtration. The solvent was evaporated under reduced pressure. The residue was purified through silica gel column chromatography (chloroform-methanol), to thereby give the title compound as an oily product (1.39 g, 57%).
