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 azetidine-1-sulfonamide, the title compound was obtained as a colorless solid (0.043 g, 13%): 1H NMR (300 MHz, CDCl3) δ 8.66 (d, J=16.5 Hz, 1H), 7.88 (d, J=9.3 Hz, 1H), 6.54 (d, J=14.6 Hz, 1H), 4.24 (t, J=7.7 Hz, 4H), 3.69-3.58 (m, 1H), 3.49 (s, 2H), 2.39-1.99 (m, 10H), 1.87-1.64 (m, 13H); MS (ES−) m/z 475.2 (M−1).
