Following the procedure as described in Example 332 Step 7 and making non-critical variations to replace methanesulfonamide with 2-methoxyethanesulfonamide and to replace 4-((2-cyanoadamantan-2-yl)methoxy)-5-cyclopropyl-2-fluorobenzoic acid with 5-chloro-4-((2-cyanoadamantan-2-yl)methoxy)-2-fluorobenzoic acid, the title compound was obtained following trituration with a 5:1 mixture of hexanes in diethyl ether (10 mL) as a colorless powder (0.094 g, 63%): 1H NMR (300 MHz, DMSO-d6) δ 12.13 (br s, 1H), 7.70 (d, J=7.4 Hz, 1H), 7.40 (d, J=12.2 Hz, 1H), 4.54 (s, 2H), 3.70 (s, 4H), 3.18 (s, 3H), 2.15-2.07 (m, 4H), 1.97-1.78 (m, 6H), 1.70-1.60 (m, 4H); MS (ES−) m/z 483.2, 485.2 (M−1).
