Reaction Steps

A mixture of 4.4 g of Intermediate XXXIV, 2.5 g of 1-(2-methoxyphenyl)-piperazine, 1 g of potassium iodide and 1.8 g of anhydrous potassium carbonate in 40 ml of dimethylformamide was stirred at 100° C. for 3 hours. After cooling to 20°-25° C., the reaction mixture was poured into 350 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 column chromatography on silica gel, eluting with ethyl acetate: petroleum ether 3:2, and by crystallization from ethanol, yielding 3.9 g of the title compound, m.p. (70) 96°-99° C.
