Methyl 4-(3,5-dichloro-4-ethoxybenzamido)-2-chlorobenzoate (AAA-017) (175 mg, 39%) was prepared in essentially the same manner as in Step (iii) for AAA-001, except that 3,5-dichloro-4-ethoxybenzoic acid was used instead of 3,5-dichloro-4-(cyclopentyloxy)benzoic acid and methyl 4-amino-2-chlorobenzoate was used instead of methyl 4-aminobenzoate: m/z 402 (M−H)− (ES−). 1H NMR (400 MHz, CDCl3) δ: 7.93 (2H, d), 7.85 (1H, s), 7.83 (1H, d), 7.80 (2H, s), 4.18 (2H, q), 3.93 (3H, s), 1.49 (3H, t).
