Reaction Steps
To a solution of ethyl 2,2-dimethyl-2,3-dihydrobenzofuran-7-carboxylate (1 g, 4.54 mmol) in trifluoroacetic acid (7 mL) at 0° C. was slowly added nitric acid (1.36 mL). The reaction was stirred at 0° C. for one hour and then at room temperature for 30 minutes. The reaction was added to ice and the resultant solid was collected by filtration, and washed with water to provide ethyl 2,2-dimethyl-5-nitro-2,3-dihydrobenzofuran-7-carboxylate (674) as a yellow solid (1.02 g, 83%).
