Komponenten

Versuchsvorschrift

A mixture of 14 mmol (3.65 g) of 3', 4'-dichloro-5-methoxyvalerophenone, 14 mmol (2.1 g) of 2-aminooxyethylamine dihydrochloride, 7 ml of pyridine and 14 ml of absolute ethanol was refluxed for 2 hours. The reaction mixture was then further processes as described in Example 4. After crystallization from a mixture of ether and petroleum ether (boiling point 40°-60° C) the above entitled compound was obtained with a melting point of 93°-94° C.
