Procedure
Methyl 3-(3-chloropropoxy)-4-methoxybenzoate (6.65 g, 25.7 mmol) was reacted with nitric acid as described in Example 16A Step 2 to give methyl 5-(3-chloropropoxy)-4-methoxy-2-nitrobenzoate (6.70 g, 22.1 mmol, 86%). 1H NMR (300 MHz, DMSO-d6) δ 7.65 (s, 1H), 7.37 (s, 1H), 4.26 (t, 2H), 3.89 (s, 3H), 3.81 (s, 3H), 3.76 (t, 2H), 2.26-2.18 (m, 2H).
