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 4-(bicyclo[4.1.0]heptan-1-ylmethoxy)-5-cyclopropyl-2-fluorobenzoic acid, the title compound was obtained following purification by reverse-phase HPLC as a colorless powder (0.037 g, 37%): 1H NMR (300 MHz, DMSO-d6) δ 11.81 (br s, 1H), 7.13 (d, J=8.3 Hz, 1H), 6.87 (d, J=13.1 Hz, 1H), 3.92-3.73 (m, 2H), 3.13-3.01 (m, 1H), 2.10-1.96 (m, 1H), 1.95-1.49 (m, 4H), 1.40-1.03 (m, 8H), 1.03-0.93 (m, 1H), 0.94-0.82 (m, 2H), 0.77-0.59 (m, 3H), 0.41-0.32 (m, 1H); MS (ES+) m/z 408.1 (M+1)
