Reaction Steps

According to the procedure described in Example 6A Step 2, to a solution of ethyl 3,4-diethoxybenzoate (6.43 g, 27 mmol) in AcOH (50 mL) was dropped fuming nitric acid (90%, 6.3 g) and the reaction was heated at 50° C. overnight, to afford ethyl 4,5-diethoxy-2-nitrobenzoate as a solid (7.175 g, 94%). 1H NMR (300 MHz, CDCl3) δ 7.44 (s, 1H), 7.05 (s, 1H), 4.37 (q, 2H), 4.18 (m, 4H), 1.50 (m, 6H), 1.35 (t, 3H); LC-MS (ESI) m/z 284 (M+H)+.
