Procedure
A mixture of 46.0 g of 3-(2,3-epoxy-propoxy)-2-nitropyridine and 35.0 g of 1-(4-piperidyl)-imidazolidin-2-one in 500 ml of isopropanol is refluxed for 2 hours. Working up analogously to Example 1 using methylene chloride as the extracting agent yields crude 1-{1-[2-hydroxy-3-(2-nitro-3-pyridyloxy)-propyl]-4-piperidyl}-imidazolidin-2-one, which after recrystallisation from isopropanol melts at 154°-158°.
