Reaction Steps

A mixture of 15.0 g (74.1 mmol) of methyl 3-ethoxy-4-methoxybenzoate in 45 mL of acetic acid was treated with 15 mL of conc nitric acid dropwise over 12 min. The reaction was kept at 55° C. for 45 min, cooled to 25° C. and poured into ice water. The product was extracted into methylene chloride and the extracts were washed with water and μl sodium hydroxide, dried and evaporated. The yield was 17.8 g of methyl 5-ethoxy-4-methoxy-2-nitrobenzoate as yellow crystals: mass spectrum (electrospray, m/e): M+H 256.0.
