Following the procedure as described in Example 299 Step 2 and making variations as required to replace 4-(adamantan-1-ylmethoxy)-2-fluoro-5-iodobenzoic acid with 4-(cyclopentylmethoxy)-5-cyclopropyl-2-fluorobenzoic acid and to replace azetidine-1-sulfonamide with 2-methoxyethanesulfonamide, the title compound was obtained as a colorless solid (0.039 g, 12%): 1H NMR (300 MHz, DMSO-d6) δ 11.88 (br s, 1H), 7.10 (d, J=8.3 Hz, 1H), 6.93 (d, J=13.0 Hz, 1H), 3.96 (d, J=6.8 Hz, 2H), 3.71 (s, 4H), 3.21 (s, 3H), 2.42-2.26 (m, 1H), 2.07-1.96 (m, 1H), 1.86-1.73 (m, 2H), 1.68-1.47 (m, 4H), 1.44-1.30 (m, 2H), 0.92-0.84 (m, 2H), 0.70-0.62 (m, 2H); 19F NMR (282 MHz, DMSO-d6) δ −113.0 (s, 1F); MS (ES−) m/z 398.2 (M−1).
