Procedure

The title compound was prepared by reacting the compound of Example 76, supra, (0.45 g, 1.0 mmol) with 4-(piperdin-1-yl)piperidine (2.0 g, 11.9 mmol) in the presence of the base N,N-diisopropylethylamine, tetra-n-butylammonium iodide and acetonitrile at 80° C. After incubating overnight at 80° C. the reaction was washed with water (2×500 ml), followed by a wash with a saturated sodium chloride solution (1×500 ml). The organic phase was then dried over potassium carbonate and the solvents were removed in vacuo to yield a light brown oil. The desired product was purified by chromatography and triturated with diethyl ether to yield a light brown powder, which was removed by filtration and washed with diethyl ether to yield the purified title compound. MS 584, 585, NMR, IR, mp 143° C.
