Procedure

Using the same procedure as described in Example 4, 17 parts of 2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one and 32 parts of n-octadecyl isocyanate were reacted together and afforded 4-n-octadecylcarbamoyl-2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one as a colourless solid which was recrystallised from petroleum ether (of boiling range 60° to 80°C) and had a melting point of 56.5°-58°C. This material gave the following elemental analysis by weight:
