A solution of 5-chloro-4-((7,7-dimethyl-5,6,7,8-tetrahydronaphthalen-2-yloxy)methyl)-2-fluorobenzoic acid (50 mg, 0.14 mmol), dimethyl(sulfamoyl)amine (326 mg, 0.20 mmol), 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (38 mg, 0.20 mmol) and 4-dimethylaminopyridine (38 mg, 0.20 mmol) in DCM (3 mL) was stirred at room temperature for 16 hrs. The reaction was quenched with water (5 mL), adjusted pH to 5 with HCl (1M) and extracted with DCM (30 mL×3). The combined organic layers were concentrated and purified by reverse phase combiflash (20%-50% MeCN in 0.1% formic acid) to give the desired product (14.6 mg, 19%) as a white solid. LCMS (ESI) Method A: RT=6.47 min, m/z 466.9 [M−H]+; 1H-NMR (500 MHz, MeOD-d4) δ 7.63 (d, J=5.5 Hz, 1H), 7.32 (d, J=11.0 Hz, 1H), 6.91 (d, J=8.5 Hz, 1H), 6.66-6.63 (m, 1H), 6.56 (d, J=2.0 Hz, 1H), 5.03 (s, 2H), 2.83 (s, 6H), 2.64 (t, J=13.0 Hz, 2H), 2.40 (s, 2H), 1.46 (t, J=13.5 Hz, 2H), 0.88 (s, 6H).
