실험 절차

A mixture of 1.1 g of 2-(chloromethyl)-4-bromoanisole, 1 g of 1-(2-pyrimidyl)piperazine dihydrochloride and 2.0 mL N,N-diisopropylethylamine in 10 mL chloroform was heated at reflux temperature for 2 hr, cooled to room temperature, washed with 1 N NaOH and water. The solvent was removed by evaporation under reduced pressure to yield 3.6 g of 2-[(4-(2-pyrimidinyl)-piperazinyl)methyl]-4-bromoanisole as a white solid which was used in the next step without further purification.
