Following the procedure as described in Example 332 Step 7 and making non-critical variations to replace methanesulfonamide with cyclopropanesulfonamide and to replace 4-((2-cyanoadamantan-2-yl)methoxy)-5-cyclopropyl-2-fluorobenzoic acid with 5-cyclopropyl-4-((4,4-difluorocyclohexyl)oxy)-2-fluorobenzoic acid and to replace methanesulfonamide with azetidine-1-sulfonamide, the title compound was obtained as a colorless solid (0.092 g, 46%): 1H NMR (300 MHz, DMSO-d6) δ 11.58 (br s, 1H), 7.14-7.06 (m, 2H), 4.80 (br s, 1H), 4.00 (t, J=7.7, 7.7 Hz, 4H), 2.18-1.87 (m, 11H), 0.89-0.82 (m, 2H), 0.67-0.61 (m, 2H); 19F NMR (282 MHz, DMSO-d6) δ −92.0 (d, J=232 Hz, 1F), −98.5 (d, J=231 Hz, 1F), −112.7 (s, 1F); MS (ES−) m/z 431.1 (M−1).
