Following the procedure as described in Example 332 Step 7 and making non-critical variations to replace methanesulfonamide with azetidine-1-sulfonamide and to replace 4-((2-cyanoadamantan-2-yl)methoxy)-5-cyclopropyl-2-fluorobenzoic acid with 5-chloro-4-((4,4-difluorocyclohexyl)oxy)-2-fluorobenzoic acid, the title compound was obtained as a colorless solid (0.028 g, 19%): 1H NMR (300 MHz, DMSO-d6) δ 11.80 (br s, 1H), 7.78 (d, J=7.5 Hz, 1H), 7.38 (d, J=12.4 Hz, 1H), 4.85 (br s, 1H), 4.00 (t, J=7.7, 7.7 Hz, 4H), 2.18-1.86 (m, 10H); 19F NMR (282 MHz, DMSO-d6) δ −92.2 (d, J=231 Hz, 1F), −98.5 (d, J=231 Hz, 1F), −110.1 (s, 1F); MS (ES−) m/z 425.1, 427.1 (M−1).
