1024 g aniline, 980 g ethylcarbamate, 1060 g ethanol (approximately 96%) and 6.0 g zinc octoate were reacted in the apparatus described in Example 1 for 6.5 hours at 200° C. When the apparatus had cooled and the pressure had been reduced, the reaction mixture was removed, filtered and analyzed by high pressure liquid chromatography (HPLC). A yield of 1580 g (87% of the theoretical yield) of N-phenyl-carbamic acid-ethyl ester was obtained.
