실험 절차

A mixture of 5-chloro-4-((2,2-dimethylchroman-7-yloxy)methyl)-2-fluorobenzoic acid (50 mg, 0.14 mmol), dimethyl(sulfamoyl)amine (26 mg, 0.21 mmol), N,N-Diisopropylethylamine (54 mg, 0.42 mmol) and 2-(7-aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (106 mg, 0.28 mmol) in DMF (2.5 mL) was stirred at room temperature for 16 hrs. The mixture was diluted with HCl (2.0 N, 20 mL) and extracted with EtOAc (50×3 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated. The residue was purified by reverse phase combiflash (15%-25% MeCN in 0.5% NH4HCO3) to give target product (11.8 mg, 18%) as a white solid. LCMS (ESI) Method A: RT=5.57 min, m/z: 471.2 [M+H]; 1H-NMR (500 MHz, MeOH-d4,): δ 7.62 (d, J=6.0 Hz, 1H), 7.31 (d, J=10.5 Hz, 1H), 6.87 (d, J=8.5 Hz, 1H), 6.40 (dd, J=8.0, 2.5 Hz, 1H), 6.24 (d, J=2.5 Hz, 1H), 5.02 (s, 2H), 2.86 (s, 6H), 2.61 (t, J=7.0 Hz, 2H), 1.68 (t, J=7.0 Hz, 2H), 1.20 (s, 6H).
