Reaction Steps

A mixture of 4 g of Intermediate XVIII, 2.4 g of 1-(2-methoxyphenyl)-piperazine, 1.96 g of potassium iodide and 1.65 g of anhydrous potassium carbonate in 40 ml of anhydrous dimethylformamide was stirred at 90° C. for 7 hours. After cooling to ambient temperature, the mixture was poured into water and extracted with dichloromethane. The combined extracts were washed with aqueous sodium chloride solution, dried on anhydrous sodium sulfate and evaporated to dryness in vacuo. The residue was crystallized from ethyl acetate and the collected crystals were dissolved in ethanol and treated with excess ethanolic hydrogen chloride to give 5.21 g of the title compound, m.p. 199-°201! C.
