Komponenten

Versuchsvorschrift

1.33 ml N-(2-aminoethyl)-morpholine, 2.2 g 3-hydroxycarbonylmethoxy-5-phenylpyrazole and 4.3 ml triethylamine were added in this order to 3.06 g 1-methyl-2-chloropyridinum iodide in methylene chloride. The reaction mixture was then heated to boiling for 3 hours under reflux. After cooling and washing with aqueous sodium hydroxide solution, the organic phase was evaporated, and the crude product obtained was purified chromatographically. 2.3 g 3-(2-morpholinoethylaminocarbonylmethoxy)-5-phenyl-pyrazole were obtained as an oily base. IR-spectrum (as film): 3205 cm-1, 1660 cm-1.
