4-(3-Chloro-4,5-bis(cyclohexyloxy)benzamido)benzoic acid (AAA-047) (15 mg, 19%) was prepared from methyl 4-(3-chloro-4,5-bis(cyclohexyloxy)benzamido)benzoate (8) (80 mg, 0.17 mmol) using a procedure essentially the same as in Step (ii) for AAA-001, except that 1,4-dioxane (6 mL) was used instead of THF: m/z 470 [M−H]− (ES−); 1H NMR (400 MHz, DMSO-d6) δ: 12.72 (1H, br s), 10.44 (1H, s), 7.94 (2H, d), 7.87 (2H, d), 7.67 (1H, d), 7.53 (1H, d), 4.53 (1H, m), 4.36 (1H, m), 1.98-1.82 (4H, m), 1.80-1.65 (4H, m), 1.58-1.20 (12H, m).
