Following the procedure as described in Example 332 Step 7 and making non-critical variations to replace methane sulfonamide with azetidine-1-sulfonamide and to replace 4-((2-cyanoadamantan-2-yl)methoxy)-5-cyclopropyl-2-fluorobenzoic acid with 5-cyclopropyl-2-fluoro-4-((1-fluorocyclohexyl)methoxy)benzoic acid, the title compound was obtained following purification by reverse-phase HPLC as a colorless powder (0.037 g, 37%): 1H NMR (300 MHz, DMSO-d6) 11.64 (br s, 1H), 7.15 (d, J=8.3 Hz, 1H), 7.02 (d, J=8.3 Hz, 1H), 4.16 (d, J=8.3 Hz, 2H), 4.05 (dd, J=8.3, 4H), 2.25-1.82 (m, 5H), 1.78-1.45 (m, 7H), 1.41-1.21 (m, 1H), 0.96-0.86 (m, 2H), 0.75-0.63 (m, 2H); MS (ES+) m/z 429.1 (M+1)
