Reaction Conditions

Reaction Steps

A stirred mixture of 178 g of ethyl carbamate, 94 g of norbornene, 5 g of ethanol and 20 g of ®LEWASORB AC-10 was heated to 70° C. in a stirred reactor, and stirring was continued at this temperature for 7 hours. Thereafter, the catalyst was filtered off and the mixture was distilled under reduced pressure. 157 g (86% of theory) of ethyl N-norbornylcarbamate of boiling point 148°-150° C./20 mbar and melting point 50° C. (from pentane) were obtained. No substantial amount of norbornene oligomers was detected.
