실험 절차

A solution of 4-(4-chloro-2-cyano-phenyl)-piperazine-1-carboxylic acid tert-butyl ester (0.32 g, 1 mmol) in dichloromethane cooled at 0° C. was treated with trifluoroacetic acid (20%) and warmed to room temperature and stirred for 2 h. The reaction mixture was concentrated in vacuo, diluted with ethyl acetate and free based with 10% aqueous sodium bicarbonate. The organic layers were separated and dried over sodium sulfate and concentrated in vacuo. The product used without further purification.
