Versuchsvorschrift
Using the same conditions as Example 1, 34 parts of 2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one and 26 parts of phenylisocyanate afforded 49 parts of 4-phenylcarbamoyl-2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one as an almost colourless solid. Crystallisation from petrol ether (40°-60°) yielded crystalline material of melting point 68.5° - 70°C which gave the following elemental analysis by weight:
