실험 절차

A solution of 3.8 g of Intermediate XXXV and 4 g of 1-(2-methoxyphenyl)-piperazine in 40 ml of dimethylformamide was heated at 60° C. for 7 hours. After cooling to 20°-25° C., the reaction mixture was poured into 500 ml of water and extracted with dichloromethane. The organic extracts were washed with water and dried on anhydrous sodium sulfate, and the solvent was then evaporated off in vacuo. The residue was purified by flash chromatography on silica gel, eluting with ethyl acetate:petroleum ether (1:1). The base of the title compound was obtained. It was dissolved in ethanol and one equivalent of ethanolic hydrogen chloride was added to give 4.5 g of the title compound, m.p. (215) 226°-228C.
