Procedure

41.3 Gm. (0.2 mole) of dicyclohexylcarbodiimide, 72.4 gm. (0.3 mole) of bis-2-ethylhexylamine, and 200 ml. of t-butanol were refluxed for 7 hours. The t-butanol was distilled off at atmospheric pressure and the residue stripped to a temperature of 180° C. at 0.08-0.09 mm Hg. The residue weighed 60.8 gm. and was 90% pure by NMR with a trace of amine and approximately 5% dicyclohexylcarbodiimide.
