Following the procedure as described in Example 332 Step 7 and making non-critical variations to replace 4-((2-cyanoadamantan-2-yl)methoxy)-5-cyclopropyl-2-fluorobenzoic acid with 5-cyclopropyl-4-(((1RS,6SR)-7,7-difluorobicyclo-[4.1.0]heptan-1-yl)methoxy)-2-fluorobenzoic acid and to replace methanesulfonamide with cyclopropanesulfonamide, the title compound was obtained as a white gum (0.030 g, 23%): 1H NMR (300 MHz, DMSO-d6) δ11.82 (br s, 1H), 7.12 (d, J=8.3 Hz, 1H), 6.92 (d, J=12.9 Hz, 1H), 4.17-3.92 (m, 2H), 3.10-2.97 (m, 1H), 2.04-1.54 (m, 6H), 1.34-1.15 (m, 4H), 1.14-1.02 (m, 4H), 0.92-0.80 (m, 2H), 0.72-0.62 (m, 2H); MS (ES+) m/z 444.1 (M+1).
