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 4-(adamantan-2-yl)-3-chlorobenzoic acid, the title compound was obtained following trituration with hexanes as a colorless solid (0.11 g, 66%): 1H NMR (300 MHz, DMSO-d6) δ 11.81 (s, 1H) 7.98-7.97 (m, 1H), 7.88-7.85 (m, 1H), 7.72 (d, J=8.2 Hz, 1H), 7.64-7.60 (m, 1H), 3.22 (s, 1H), 2.50 (d, J=4.4 Hz, 3H), 2.23 (s, 2H), 1.95-1.85 (m, 8H), 1.72 (s, 2H), 1.63-1.59 (m, 2H); MS (ES−) m/z 381.2, 383.2 (M−1).
