Reaction Steps

5.5 Parts of 7,14-diazadispiro[5.1.5.2]pentadecan-15-one, 3.2 parts of n-hexylisocyanate and a trace of 1,4-diazabicyclo[2.2.2]octane in 100 parts of dry benzene were heated at reflux for 36 hours. The solvent was evaporated in vacuo and the residue stirred with 100 parts of water for 24 hours. This phase was extracted three times with 100 parts of chloroform and the extracts dried over magnesium sulphate. Evaporation of the solvent in vacuo gave an oil which was distilled at 157°C (0.3 mm pressure). This liquid, 14-n-hexylcarbamoyl-7,14-diazadispiro[5.1.5.2]pentadecan-15-one, gave the following elemental analysis by weight:
