실험 절차

Following the procedure of Example 5, a mixture of 5-(4-chlorobutyl)-3-(1-methylethyl)-2-oxazolidinone (10.4 g, 0.0474 mol), 1-(2-hydroxyphenyl)piperazine dihydrobromide (16.12 g, 0.0474 mol), sodium bicarbonate (15.96 g, 0.190 mol) and potassium iodide (1.0) in n-butanol (350 mL) gave an oil. The oil was dissolved in absolute ethanol and acidified with ethanolic hydrogen chloride. Addition of ether and filtration gave a solid which was dried under high vacuum at 70° C. to give 9.47 g (46% yield), mp 203°-207° C.
