Reaktionsschritte

After completion of the reaction, 1% hydrochloric acid (23 g) was dropwide added at 10° C. or lower and after stirred for 30 minutes, settled and separated. The obtained organic layer was washed with 9% salt water (7 g) at 5 to 10° C., settled and separated. The obtained organic layer was washed with an aqueous 5% sodium hydrogen carbonate solution (11.8 g) at 15 to 30° C., settled and separated. After that, the organic layer was washed with ion-exchange water (6 g) at 25 to 35° C., settled and separated. The obtained organic layer was evaporated to obtain a solution (10.04 g) of a desired pale yellowish transparent solution or white solid. The content was found 86.5% by gas chromatography analysis. The pure product yield was 8.68 g (yield 87.8% based on acetic acid). The content of impurities are as follows: diisobutylcarbonate: 2.0%, and N-isobutyloxycarbonyl)-benzylamine: 2.5%.
