실험 절차

A mixture of 2-[2-(4-propionoxy-4-phenylpiperidino)ethylamino]benzamide (12.55 g), benzaldehyde (3.55 g), piperidine (1.35 g), and absolute ethanol (80 ml) was refluxed for 30 hrs. The solvent was removed on a rotovap. The thick oily product was chromatographed using silica gel and 5% isopropanol in chloroform. The product was isolated and dissolved in 30 ml 95% ethanol The solution was made acid with 4N H2SO4 and then 90 ml H2O was added. After 1 hr, the product was isolated and recrystallized from 850 ml 95% ethanol; yield 8.7 g, m.p. 186°-189° (d).
