실험 절차

15 mol of eugenol was charged into a pressure reactor, along with 0.2 mol of 1,8-diazabicyclo[5.4.0]-7-undecene and 16 mol of dimethyl carbonate. The reactor was sealed and was heated to 150° C. After 2 hr, complete conversion of the eugenol was shown to have occurred. After the distillation, 13 mol of eugenol methyl ether and 1 mol of isoeugenol methyl ether were obtained, corresponding to a yield of 86%, based on the starting amount of eugenol.
