4-(4-Chloro-3-isopropoxy-5-methoxybenzamido)benzoic acid (AAA-118) (10 mg, 55%) was prepared from methyl 4-(4-chloro-3-isopropoxy-5-methoxybenzamido)benzoate (5) (20 mg, 48 μmol) using a procedure essentially the same as in step (ii) for AAA-001 except that dioxane (3 mL) was used instead of THF: m/z 362 [M−H]− (ES−); 1H NMR (400 MHz, DMSO-d6) δ: 12.80 (1H, br s), 10.47 (1H, s), 7.99-7.92 (2H, m), 7.90-7.83 (2H, m), 7.31 (2H, dd), 4.79 (1H, sep), 3.94 (3H, s), 1.33 (6H, d).
