Participants

Reaction Steps

Using the same conditions as in Example 4, 2.76 parts of 1,2,2,7,7 -pentamethyl-1,4-diazacycloheptan-5-one and 0.93 parts of methyl isocyanate afforded a colourless solid which was crystallised from petroleum ether (of boiling range 60°-80°C) to give 4-methylcarbamoyl-1,2,2,7,7-pentamethyl-1,4-diazacycloheptan-5-one. This material had a melting point of 111°-113°C and gave the following elemental analysis by weight:
