Following the procedure of Example 1, the title compound is prepared from a mixture of 5-(4-chlorobutyl)-3-methyl-2-oxazolidinone (5.0 g, 0.0262 mol), 1-(2-pyridinyl)piperazine (4.56 g, 0.0279 mol) and potassium carbonate (8.5 g, 0.0614 mol) in 1-butanol (50 ml) to obtain 3.4 g (41% yield) of solid. Recrystallization from ethyl acetate/petroleum ether followed by drying in vacuo gave 1.46 g of the title compound, mp 69°-72° C.
