Procedure

Cyclopentadiene of Formula VI and 2-hydroxyethylacrylate of the following formula VII were dissolved at a same rate in ether or tetrahydrofuran. Thereafter, this was reacted at a temperature of about -30 to 60° C. for 24 hours. Thereafter, the solvent was removed by use of a rotary evaporator and the residues were distilled in vacuo to give 2-hydroxyethyl 5-norbornene-2-carboxylate of the following formula VIII which was in an endo- and exo-mixture. ##STR5##
