Reaktionsschritte
10 mol of 2-nitrophenol was charged into a stirred, heated reactor, along with 800 ml of nonane and 5% N,N'-dimethylbenzoamidine, and the mixture was heated to 150° C. Then 12 mol of dimethyl carbonate was added portionwise over 5 hr. The methanol produced by the reaction was removed by distillation over a distillation column. After completion of the reaction, the reaction mixture was refined by distillation. 2-Nitroanisole was obtained in the amount of about 9 mol, corresponding to a yield of c. 90%, based on the starting amount of 2-nitrophenol.
