Participants

Reaction Steps

To a solution of sodium hydroxide (4.6 g, 115 mmol) in water (35 mL) was added the Intermediate from Step C (2.35 g, 14.4 mmol). A solution of hydrogen peroxide (30%, 21 mL) was then added over 30 minutes. The reaction was neutralized to pH 7 by the addition of diluted hydrochloric acid (1N). The precipitate was collected and dried to afford the product 4-aminobenzo[d][1,3]dioxole-5-carboxylic acid (1.68 g, yield 64%). 1H NMR (400 MHz, DMSO-d6) δ ppm 7.40-7.42 (d, 1H, J=8.4 Hz), 6.25-6.27 (d, 1H, J=8.4 Hz), 6.04 (s, 2H).
