Procedure

Following the procedure as described in Example 271 and making variations as required to replace 6-(adamantan-1-ylmethoxy)-5-cyclopropylnicotinic acid with 4-(adamantan-1-ylmethoxy)-5-(2,2-difluorocyclopropyl)-2-fluorobenzoic acid and to replace 2-methoxyethanesulfonamide with methyl sulfonamide. Purification by silica gel column chromatography (2:1 hexanes:ethyl acetate (+0.2% acetic acid v/v)) gave the title compound as a colorless solid (0.070 g, 58%): 1H NMR (300 MHz, DMSO-d6) δ 11.93 (br s, 1H), 7.45 (d, J=8.2 Hz, 1H), 7.00 (d, J=13.0 Hz, 1H), 3.71-3.54 (m, 2H), 3.31 (s, 3H), 2.85-2.71 (m, 1H), 2.03-1.87 (m, 5H), 1.75-0.155 (m, 12H); MS (ES+) m/z 458.1 (M+1).
