Following the procedure as described in Example 332 Step 7 and making non-critical variations to replace methanesulfonamide with cyclopropanesulfonamide and to replace 4-(((1r,3r,5r,7r)-2-cyanoadamantan-2-yl)methoxy)-5-cyclopropyl-2-fluorobenzoic acid with 5-chloro-4-((4,4-difluorocyclohexyl)oxy)-2-fluorobenzoic acid and methanol with cyclopropyl sulfonamide, the title compound was obtained as a colorless solid (0.047 g, 31%): 1H NMR (300 MHz, DMSO-d6) δ 12.02 (br s, 1H), 7.75 (d, J=7.5 Hz, 1H), 7.37 (d, J=12.6 Hz, 1H), 4.85 (br s, 1H), 3.07-2.98 (m, 1H), 2.07-1.87 (m, 8H), 1.09-1.05 (m, 4H); 19F NMR (282 MHz, DMSO-d6) δ −92.3 (d, J=231 Hz, 1F), −98.5 (d, J=231 Hz, 1F), −109.9 (s, 1F); MS (ES−) m/z 410.0, 412.0 (M−1).
