Versuchsvorschrift
Following the procedure of Example 1, mixture of 5-(4-chlorobutyl)-3-methyl-2-oxazolidinone (5.0 g, 0.0262 mol), 1-(2-pyrimidinyl)piperazine dihydrochloride (6.62 g, 0.0279 mol), potassium carbonate (19.3 g, 0.140 mol) and potassium iodide (0.75 g) in 1-butanol (75 ml) gave an oil (3.0 g) which crystallized upon standing. Recrystallization from ethyl acetate/light pet ether followed by drying under high vacuum gave 1.33 g (16% yield), mp 74°-76° C.
