Reaction Steps

A solution of 4-amino-phenyl acetic acid methyl ester (3 g, 18.2 mmol) in acetic anhydride (16 mL) was stirred at room temperature for 30 minutes. The reaction mixture was cooled to 0° C. temperature and fuming nitric acid (2.3 mL) was added dropwise. The ice bath was removed and the reaction mixture was stirred for another 20 minutes before pouring it onto iced water. The resulting yellow precipitate was filtered, washed with water and dried in vacuo at 50° C. to give 3.7 g of the product. 1H NMR 500 MHz (DMSO) δ 2.05 (s, 3H), 3.63 (s, 3H), 3.81 (s, 2H), 7.54 (d, 1H), 7.58 (dd, 1H), 7.87 (d, 1H), 10.2 (s, 1H).
