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-(((1SR,6RS)-7,7-difluorobicyclo-[4.1.0]heptan-1-yl)methoxy)-2-fluorobenzoic acid and to replace methanesulfonamide with azetidine-1-sulfonamide, the title compound was obtained as a white gum (0.051 g, 81%): 1H NMR (300 MHz, CDCl3) δ 8.65 (s, 1H), 7.64 (d, J=9.1 Hz, 1H), 6.54 (d, J=14.1 Hz, 1H), 4.25 (t, J=7.9 Hz, 4H), 3.98 (s, 2H), 2.32-2.22 (m, 2H), 2.09-2.00 (m, 1H), 1.96-1.57 (m, 4H), 1.49-1.25 (m, 5H), 0.98-0.92 (m, 2H), 0.72-0.67 (m, 2H); MS (ES+) m/z 459.1 (M+1).
