Following the procedure as described in Example 332 Step 7 and making non-critical variations to replace methanesulfonamide with methyl sulfamide 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 diethyl ether (10 mL) as a colorless powder (0.073 g, 52%): 1H NMR (300 MHz, DMSO-d6) δ 11.72 (s, 1H), 7.73-7.66 (m, 2H), 7.34 (d, J=12.2 Hz, 1H), 4.54 (s, 2H), 2.53 (d, J=4.6 Hz, 3H), 2.15-2.07 (m, 4H), 1.97-1.78 (m, 6H), 1.70-1.60 (m, 4H); MS (ES−) m/z 454.1, 456.1 (M−1).
