Versuchsvorschrift

Using the same conditions as in Example 4, 17 parts of 2,2,7,7 -tetramethyl-1,4-diazacycloheptan-5-one and 8 parts of ethylisocyanate afforded an almost colourless oil which was distilled in vacuo to yield 20 parts of 4-ethylcarbamoyl-2,2,7,7-tetramethyl-1,4diazacycloheptan-5-one of boiling point 103° - 107°C at 1mm pressure. This material gave the following elemental analysis by weight:
