Ethyl 4-((5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazol-2-ylthio)methyl)-3,5-difluorophenylsulfonylcarbamate (76 mg, 0.12 mmol, 1.0 eq) and 4-aminomorpholine (0.045 mL, 0.46 mmol, 4.0 eq) in toluene (2.5 mL, anhyd) were heated at reflux for 2.5 h. The reaction mixture was cooled to room temperature, diluted with EtOAc and washed with water, followed by brine. After drying (MgSO4), the organics were concentrated and purified by chromatography (silica, 0 to 80% EtOAc/Hex, then 10% MeOH/DCM) to provide the title compound (40 mg). 1H NMR (400 MHz, DMSO-d6) δ 8.33 (s, 1H), 7.41-7.16 (m, 4H), 7.03-6.90 (m, 3H), 6.57-6.43 (m, 4H), 4.02-3.98 (m, 2H), 3.71-3.65 (m, 3H), 3.57-3.50 (m, 3H), 3.48-3.38 (m, 1H), 3.31-3.25 (m, 1H), 2.69-2.58 (m, 3H), 1.46 (s, 6H); MS (EI) m/z 710.1 (MH+).
