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 4-(adamantan-1-ylmethoxy)-5-cyclobutyl-2-fluorobenzoic acid and to replace methanesulfonamide with cyclopropanesulfonamide, the title compound was obtained as a colorless solid (0.090 g, 35%): 1H NMR (300 MHz, CDCl3) δ 8.69 (d, J=16.3 Hz, 1H), 7.87 (d, J=9.3 Hz, 1H), 6.53 (d, J=14.71H), 3.69-3.56 (m, 1H), 3.49 (s, 2H), 3.15-3.06 (m, 1H), 2.39-2.29 (m, 2H), 2.18-1.98 (m, 6H), 1.87-1.65 (m, 13H), 1.48-1.42 (m, 2H), 1.17-1.10 (m, 2H); MS (ES−) m/z 460.2 (M−1).
