실험 절차

A solution of 1-(1,4-benzodioxan-5-yl)piperazin (11 g) and triethylamine (7 ml) in N-methyl-2-pyrrolidinone was treated dropwise with chloroacetonitrile (4.5 g). After stirring for 2 h at 100° C. the mixture was poured onto ice and extracted with ethyl acetate. The organic phase was washed with water, dried over magnesium sulfate, filtered, and concentrated in vacuo. The product, 1-(1,4-benzodioxan-5-yl)-4-cyanomethylpiperazine, was obtained as an oil (17.4 g) which was sufficiently pure for use in the next step.
