実験手順
1.1 g of 2-chloro-3-(2,3-epoxy-propoxy)-6-methylpyridine and 0.76 g of 1-(4-piperidyl)-imidazolidin-2-one are refluxed in 40 ml of isopropanol for 1 hour. Evaporating off the solvent and recrystallising the residue from the isopropanol/ether yields 1-{1-[2-hydroxy-3-(2-chloro-6-methyl-3-pyridyloxy)-propyl]-4-piperidyl}-imidazolidin-2-one with a melting point of 175°-180°.
