Participants

Reaction Steps

0.46 g of cyanamide are added to a solution of 3.5 g of N-(2,6-diisopropyl-4-phenoxyphenyl)-N'-tert-butylcarbodiimide [prepared in accordance with Example 1 (compound 4) of European patent application A-175 649] in 20 ml of 1,2-dichloroethane. The reaction mixture is refluxed for 21 hours and then concentrated by evaporation to a suspension. This concentrated suspension is stirred with diethyl ether and the crystalline product so obtained is filtered with suction. Melting point 206°-207° C. (recrystallisation from diethyl ether/hexane).
